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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
