Yesterday, I got two new types of snails for my aquariums. The first is one that I’ve been looking at for a little while, but only recently had the opportunity to obtain. The Sun Snail has little horns or spikes spiraling off of the their shells.

The bag that I got them in was actually punctured by the spikes. From what I’ve read, these snails should be similar to the Olive Nerite Snails in terms of their algae eating ability. In addition, I don’t think that they will reproduce in fresh water.

The other type of snail that I got was the Tiger Snail, named for the orange and black pattern on their shells. These seem to be larger than the Olive Nerite, and much larger than the Sun Snails.

As such, they have a larger foot, and can really propel themselves across the substrate. I’ve also found two of them outside of my tank, thus far, hanging out on the light fixture above the tank, and on the rim of the tank. I suppose that means that they’re still adjusting to the water in my tank.

While these snails really just serve the same purpose as their Olive Nerite cousins, they add a little bit of variety to the options we have for snails in our tanks.

Two weeks ago, I posted a rather pathetic version of my 2.5G aquascape. I got some great comments from everyone, and have updated the scape in a few areas. It’s amazing the difference that the Blyxa japonica, in particular, makes in this scape in the back left. Otherwise, I added some Anubias barteri var. ‘nana’ and moved all of the Java Fern to the right side of the tank. What do you think?

I also decided to practice some of my photography skills for this picture. With these smaller tanks, you really have the luxury of being able to flash the heck out of the whole tank evenly, using just a couple of strobes. You can see my setup below. I sat one flash on top of the light fixture pointing upward into a domed piece of computer paper. The dome reflects the flash down the back of the tank, illuminating the white paper background sitting about 3-4 inches behind the aquarium.

Then, I have a second strobe suspended, using an improvised snoot to focus the light into the tank, which illuminates the front of the scape, which would normally be shaded by the rocks. Of course, the aquarium light itself provides pretty decent light as well, so these strobes are really just for a bit extra refinement. Any suggestions?

My wife recently got back from a work-related conference in San Francisco, CA. While she was there, she quite awesomely went to one of the premiere planted aquarium stores in the United States to check out their plant selection and take some pictures.

After spending nearly 30 minutes on the phone with me, reading off (and butchering quite humorously) countless Latin plant names, I finally had a list for her of the ones I wanted. Basically, I was looking for any plant that I either haven’t heard of, or wasn’t entirely sure if could be a variation a plant I’ve seen.

We ended up with the following:

• Hygrophila sp. (Looks like ‘Porto Vehlo’ to me.)
• Ranunculus paplentus (Looks like ‘R. inundatus’ to me.)
• Limnophila sp. “Broad Leaf”
• Limnophila sp. “Needle Leaf”
• Eriocaulaceae sp. “Large Crown”  (Looks like ‘Type 3′ to me.)
• Hygrophila balsamica var. ‘Broad Leaf’
• Nymphea sp. “Four Color”
• Melastomataceae sp. ‘Sao francisco’
• Rotala sp. ‘Araguaia’

I’ve got all of these planted now, and hope to grow them out. I can’t imagine being able to go into your local LFS and having the selection of plants that San Franciscan’s have. Truly incredible!

Otherwise, you can tell that this store knows how to grow and sell plants. Looks how every tank is packed with plants, many of them rare. Their display tanks are phenomenal, appropriately exhibiting an Amanoesque Nature Aquarium style.

Even down to the fish choice of neon tetras, ADA tanks, and glassware. My wife said that they carried the whole line of ADA aquascaping tools, but didn’t get a price on them. (I probably don’t want to know.)

In addition, she said that they had made planted tanks out of several non-conventional containers, be it standard fish bowls, vases, etc… They also had a whole selection of shrimp, which from her description sound very much like the new ones from Sulawesi.

All in all, I’m jealous that I wasn’t able to go myself, but am incredibly thankful that my wife took the time to stop in and take these pictures, and grab the plants for me. I’m a lucky man!

I’ve changed a few things around in my 75G since my previous update last month. Most noticeably, I have thinned out a ton of the Blyxa japonica that was in the front right. Overall, I think this gives the right side a little bit more definition because it allows a small amount of foreground all the way across the front of the tank. I’ve been continuing my extra attention to this tank, ensuring weekly water changes, consistent CO2 output, and regular dosing. The payoff has been increased growth and a small reduction of the black brush algae that seems to love the rocks, wood, and Anubias leaves in this tank.

As you can tell, however, I still probably need to dose more fertilizers, nitrates in particular. That is evident in the bright pink color of the Limnophila aromatica and Ludwigia glandulosa on the right side of the tank. In addition, I probably have too many species of plants in this tank. I’ve recently added Vallisneria americana var. ‘natans’ to the right side of the tank, which is supposed to be a shorter and thinner version of the otherwise monster grassy plant that is Vallisneria americana. I also planted Hygrophila sp. ‘Porto Velho‘ in the front-right of the foreground, and have a number of other species of plants jammed in, particularly on the right side. All of this said, I’m pretty happy with the direction that this aquascape is going in. I wish the Eleocharis sp. ‘Japan’ hairgrass would pick up it’s growth rate, and actually create a lush lawn in the foreground, but I suppose it’s just a matter of time for that. Comments welcome!

Jeff Ucciardo gave a wonderful overview of fertilizers at GWAPA’s August meeting this month. Jeff is a former tank-of-the-month winner on Aquatic Plant Central and is known within the club as having one of the most algae-free and well maintained set of planted aquariums in the club. Much of this is due to his grasp of how to use fertilizers to maintain the proper balance of nutrients in the aquarium. He put together a fantastic presentation, going over Estimative Index (EI) and Perpetual Preservation System (PPS) methods of dosing. Then, he described how he does something in-between those two methodologies while using an auto-doser to maintain consistency.

We also had another huge auction this month. I came away with the biggest anubias I have ever seen. This monster plant is well over 2 feet tall, and more than a foot wide. It looks like Anubias barteri in some places, but in others like a totally different species. I stuck it in the back corner of my 54G aquarium to give a little bit more height to that scape. Otherwise, I came away with Lobelia cardinalis var. ’small form’ and some pond plants. All-in-all, another great club meeting!

I last posted about my 2.5G tank about a month ago. Since then, the HC has really taken off, but it’s getting kind of out of hand, actually. The one thing I don’t like about HC is that, unlike Glossostigma elatinoides, it doesn’t trail the substrate as tightly, growing upwards a bit more instead. Of course the benefit is that HC has much smaller leaves than glosso.

It’s pretty obvious to me that the Malayan aquasoil has run out of umph. This isn’t entirely unexpected because the tank has been setup for almost 2 months now. That means that I’ve had to start dosing some Seachem fertilizers to keep things going. From the algae on the glass, you can tell that I haven’t been as consistent as I should be in this respect. The downoi has all but melted for me — again. This plant dogs me for some reason every time I try it in a nano. I suspect it’s the inconsistent dosing, or possibly the higher temperatures that the light produces in this tank. Overall, I’m kind of underwhelmed by this scape. Hopefully I’ll be able to spruce it up a little bit before October 1st when the photo is due. I love to hear suggestions for what to put on the left side.

About a month ago, I tore down my 40G aquarium’s aquascape, and redid the entire thing using earthworm castings as a base substrate, with previously used ADA Amazonia as the top layer. Below, you can see how the tank has progressed over the period of 1 month.

40G - Setup for about 1 month using earthworm castings.

Since setting it up, I have been doing weekly water changes, removing about 30-40% of the water during each change. I have been doing this because the tank has been having a terrible bout with hair algae. In addition, over the last week, I’ve been treating the tank with hydrogen perioxide, both to combat the algae, and as a preventative measure in case any of the fish I recently collected have any parasites. I’ve noticed a significant reduction in algae, although the problem continues. Despite the algae, I have witnessed fantastic plant growth over the last month. In particular, Ludwigia inclinata var. verticillata ‘Cuba’ has been particularly prolific. I trimmed right before this picture, otherwise it would be occupying the entire back right of the photo. Additionally, the Hygrophila sp. ‘Porto Velho’ and Ranalisma rostrata has been starting to fill across the foreground. I think I’m going to remove the Blyxa japonica from the right front entirely, as it looks out of place. Comments welcome!

I managed to get a few pictures of the native fish that I recently collected from the Potomac River in Virginia. I’m really happy with these fish so far. When I first put them in the tank, they went straight into the plants, not to be seen.

Blue Spotted Sunfish - Enneacanthus gloriosus

Since then, I’ve been feeding them blackworms, and have spent a lot of time in front of the tank, which seems to be getting them used to my presence. The sunnies, in particular, were quite shy to begin with. Now, it’s not unusual to see several of them out and about at the same time.

Blue Spotted Sunfish - Enneacanthus gloriosus

Many of the sunfish have also colored up quite a bit. Some of the younger ones don’t yet have their blue spots, but the older fish are actually quite striking. The little teardrop, or black stripe, under their eye reminds me of Bolivian Rams, Mikrogeophagus altispinosus.

Tessellated Darter - Etheostoma olmstedi

In general, I tend to really enjoy lazy bottom dwellers, and this Tessellated Darter, Etheostoma olmstedi, is exactly that. I love how darters prop themselves up on their front fins, and just sit there waiting for food to come along.

Tessellated Darter - Etheostoma olmstedi

He’s readily accepting blackworms, but even though I’m adding a few pellets with my other feedings to try and get him on commercial food, so far he’s not interested. The Banded Killifish, Fundulus diaphanus, are another one of the fish that are slowly calming down in my tank.

Banded Killifish - Fundulus diaphanus

When I first introduced them, they would often jump from the water when I approached the tank. Now, they’re still staying close to the plant cover, but they’re at least out in the open, while keeping a close eye on me.

Banded Killifish - Fundulus diaphanus

I’ve noticed that they have an interesting mouth that tends to open and unfold a little bit differently than other fish I’ve kept. I presume this is designed to suck surface bugs into their mouths. If I’m ever able to get a picture of it up close, I’ll post it. Overall, I’m still quite pleased with my recent acquisitions. All of the fish appear to be healthy, and should be a nice addition to my tank for some time.

After waiting for some time to finally happen, this week my Swamp Lilly (Crinum americanum) sent up four beautiful white flowers. Very fragrant, the flowers have a pleasant smell that is something like a light woman’s perfume.

The white petals are accented by several bright pink stamen, jutting out from the center. I knew that I could expect a flower soon because my fellow GWAPA member from which I received these plants, said that they usually flower in the July/August timeframe.

Right on cue, the flower stalk appeared last week. Originally, the flower stalk seems as if it would only contain a single flower, but over time, the tip of the stalk reveals four separate flower pods, which in turn contain several petals each.

I haven’t seen any bees visit the flowers yet, but since they’re all throughout my garden, I would expect them to find it soon enough. I’m curious to see whether I can obtain seeds, verses simply propagating the plant by division.

Between the lovely flower and attractive folage, I think Crinum americanum has found a permanent home in my backyard raised brick pond.

On Saturday, a few GWAPA members got together in Virginia along the Potomac River to see what fish we could pull out of the river. Armed with the necessary permits and a few experts in native fish, we started pulling seine nets through some areas near the shore. Most of the shoreline was completely consumed by Hydrilla, an incredibly invasive exotic weed from Asia.

Potomac River, Virginia

Initially, the Hydrilla was way to thick, and besides pulling a few crayfish from the water, we didn’t have a whole lot of luck. We eventually crossed the street, and found a better location a little bit upstream in a creek that feeds into the Potomac.

Large Crayfish

Once we did this, we started pulling out all kinds of fish and critters. By pulling the net through the Hydrilla we were able to target the fish we were interested in, while also doing the river a service by pulling much of the noxious weed from the water and onto the bank.

Fish in Net

The main fish I was interested in finding on this trip was the Blue Spotted Sunfish, Enneacanthus gloriosus, which is a beautiful native sunfish that only gets to 2-3 inches in length. This makes it a wonderful fish for the planted aquarium, as it should not rearrange the tank like some of the larger sunfish, and loves the cover that plants provide.

We were also hoping to find some snakeheads, not to keep for the aquarium because doing so is illegal, but to see how widespread they really were in the river. Although a bit disappointing to us, I suppose it’s a good thing that we didn’t actually pull any in our nets. Had we found any, legally, you have to euthanize them on the spot.

Banded Killifish

We did get a large number of Banded Killifish, Fundulus diaphanus, which are also good fish for the aquarium. They get to about 4 inches in length, but most of the ones we pulled in were smaller than that. In addition to the killies, we also found one or two darters, specifically, the Tessellated Darter, Etheostoma olmstedi, which are fascinating bottom dwelling fish. I really would have liked to find more of these guys.

Tessellated Darter

Besides the fish, we also pulled in a number of other aquatic creatures, including a countless number of nasty looking bugs, beetles, and dragonfly nymphs. In addition, we got some grass shrimp, Asiatic clams, and all sizes of crayfish.

Asiatic Clam

The area where we found all the fish had a number of aquatic plants including Heteranthera dubia, Vallisneria americana, Myrophyllum, Najas, and a beautifully flowering Lobelia cardinalis. While many aquarists keep the small form of Lobelia cardinalis, you can see that this would be a beautiful pond plant!

With great weather, and a good haul, we had a really great time at the Potomac River this weekend. Huge thanks go to Bob in GWAPA for organizing the trip, and to everyone else for participating. Finally, I want to thank Jeff U for taking fantastic pictures, and allowing me to use them on this website.
