Summer Tub Update: May

It has been almost a month since I began my summer tub experiment. It's in full swing now. I added the mosquitofish (Gambusia holbrooki) roughly two weeks after I started it. I put in roughly 15 fish, most of them females. They aren’t very visible, but I have seen them a couple of times when I checked on the pond. Unless I see some overcrowding, I’ll wait until the end of the summer to remove some and really take a count of how many I have in there.

The plants took off after I added the fish. The frogbit has taken over, and I recently removed a couple of handfuls. The water lettuce hasn’t done as well, but that could be because the frogbit is chocking it out. Earlier in May my iris flowered, and the potted grasses are also doing well.

Since my koi pond is simply too shaded for most plants, I have never been able to have lilies. This tub with its 5 hours of sun is my best chance to grow them. A week ago I bought a lily plant from Lowes and decided to give it a try in the tub. It has been doing great! No flowers yet, but it sprouted and has broken the surface. I’m really hoping to get a flower or two from it later this summer.

Thus far I feel this is going very well. Because of the cool spring we had I don't feel I could have added tropicals until at least May 15. It's a good thing I wasn't planning on them this year. Although I can't see the mosquitofish that well, I want something that I know will survive on my first try rather than something I will have to worry about while I get the basics down.

Full tub shot!

My Tanks: 18 May Update

The times between my updates keep stretching out because my tanks are going through fewer and fewer changes. Once every couple of months is more than enough to cover everything. That said, I only have a few things to report this week.

My comminuty tank got some new residents in the form of Amano shrimp (Caridina multidentata). The gourami did pick off a few, but the remaining three are hard at work keeping down the algae. I have a bit of staghorn algae in the tank, and they have been very diligent in eating it. Amano shrimp are much larger than cherry shrimp and do just fine with the fish.

I have also added a new plant: Hygrophilia sp tiger. It is another stem plant, but it is one of the few low-light stem plants. It's in a temporary position right now, but during the summer I'm going to put a canister on the community tank. Then the hygro can be moved to where I want it. Thanks to the sharp eye of a friend, I've also realized I have a fourth species of crypt in my tank. He pointed out that I have a C. pontederiifolia as well as the C. spiralis, C. undulata, and C. wendtii. I'm guessing it came as an extra with my last order of crypts from Aquariumplants.com.

You can see the C. pontederiifolia to the right of the rock in the center.
The hygro is in the back left. And there is a bonus amano.

The shrimp tank underwent the most changes. Because my starting population was so low, I ordered 10 sakura red shrimp from HomelessAquatics.com. They arrive in good condition and acclimated well, but I had a mass die-off like 4 days after they went into the tank. I attribute it to first-time shrimping mistakes which could have been anything from not feeding enough, feeding too much, an immature tank, pH too high. I wasn't really sure, but either way only about 3 of the original 10 are still alive. I was about to give up on shrimps when a female became berried, but she died shortly after that. I put her body in a net over the filter in an attempt to hatch her eggs like I'd read online. And it actually worked! I was able to hatch about five eggs.

As for cosmetic changes in the tank, I have also made some large ones. I added two large pieces of driftwood as well as some X-mas moss and java moss. I removed the bacopa because I just didn't like the look of it. I also added some floating plants such as frogbit and dwarf water lettuce. I currently have one berried female and a few saddled ones.

There aren't nearly as many updates as I would like with the pond because we've had a very cold spring. We even had a frost earlier this week. The plants are just flowering now. I added some water hyacinth to the pond, but it's not in top shape due to the cold weather.

The other major change in my fish tanks is a new goldfish!!! Mid April I bought a ranchu from DandyOrandas.com, and I'm in love with this little girl! She's slightly larger than my ryukin and oranda, but they are catching up fast. I have named her Ponyo, but my mother calls her Marlyn because she has a black dot on her check. She took to hand feeding extremely well, and fits in with the group perfectly. I am so happy to have her!!

Look at that cute face!!!

Like three peas in a pod.

The last and rather small (right now) change in the goldfish tank was the addition of six apple snails. A friend had too many in his tank and was giving away babies. I plopped them in while distracting the goldfish, but Ponyo was too quick and completely ate one, spitting out the operculum. So the apple snails are in a breeder box getting daily feedings so they grow large enough not to be goldfish food.

There will be something special in the next update! :3

The Beauty in your Backyard

North American Native Fishkeeping

The first time I saw picture of a darter was in my ichthyology class, second semester of my junior year. We’d just finished covering marine fishes of the eastern US and were starting on the freshwater fishes. I couldn’t believe my eyes. I never knew there were such beautiful fish right outside my door. The first time I saw a darter in the flesh, I was forever entranced.

Redfin darter Etheostoma whipplei I caught while in Arkansas

When most people think of North American fishes, largemouth bass (Micropterus salmoides) and channel catfish (Ictalurus punctatus) are the first things to come to mind. These large gamefish are the ones that are seen and talked about the most, so it is no wonder that is where most minds go first. But there is so much more in our waterways than just these well-known fish. Surprisingly a lot of these are pretty easy to keep in a tank. They don’t need heaters like tropical fishes and some can be kept in ponds year-round.

In the US we have a lot of members of the cyprinid family—minnows—that are remarkably easy to care for. They are just like the barbs and rasbora of Asia. These minnows are subdivided into dace, shiners, and chubs. They are shoaling and prefer groups of six or more. North American minnows do best in 30+ gal (113 L) tanks and for the most part are just fine with other species of minnows. My favorites are mountain redbelly dace (Chrosomus oreas), saffron shiner (Notropis rubricroceus), and turquoise shiner (Cyprinella monacha), but these are just the ones I have in my backyard.

For those that like the cute appeal of the corydoras and other tropical catfishes, there are also cute catfish in the streams of North America: the madtoms (Noturus spp). They have the typical catfish look but stay small enough for a 30 + gal (113 L) tank. Some species are spotted or speckled with a bit of color, but their most entertaining qualities are their catfish antics and their adorable whiskered faces peeking out of rock caves.

Darters (Etheostoma spp) and (Percina spp) are the gems of North America. Hands down I believe they are the most stunning fishes we have here. They have reds, blues, greens, and yellows to match some of the most beautiful tropical fishes. But they have a catch: darters come from cool, flowing water. You have to provide that if you keep them in an aquarium. This often includes powerheads or simply a river manifold. Darters are also territorial, so make sure to provide enough hiding spaces for them in a tank. In the wild, they can just swim down to the next riffle; they don’t have that luxury in a tank. I have seen a few tutorials for how to set up a darter-specific tank like this one from the North American Native Fishes Association (NANFA). Or you could just use a setup typical of hillstream loaches detailed here at Loaches Online.

When most people think sunfish, they think about bluegill (Lepomis macrochirus) or crappie (Pomoxis nigromaculatus). These large cichlid-like fish are only a few of the centracidae family found in the US. While not all of them are beautiful, there are a few worth pointing out. The pygmy sunfishes (Elassoma spp) are certainly some of the most stunning. They are the smallest fishes detailed today in this article; they can be kept in tanks as small as 10 gal (37 L). Pygmy sunfishes are also the most delicate and can prove difficult to feed. They are very shy and need a heavily planted tank with things like anarcharis, hornwort, and duckweed. They were once described to me as “not for the fishkeeper who needs to see their fish every day.” Unlike with most of these fish, you probably won’t be able to find pygmy sunfish in your backyard. They are generally restricted to coastal areas of the eastern US.

For those that like to see their fish a little more often, there are other more visible sunfish. The banded sunfish (Enneacanthus obesus) and bluespot sunfish (Enneacanthus gloriosus) are a good choice for a medium sized tank. With colors and temperament matching the South American cichlids, they make an excellent fish for a 30 gal (113 L) to 70 gal (265 L) native tank. Unlike the darters and minnows, they prefer the pools to the faster water.

Those with a much larger tank might enjoy the some of the most brightly colored Lepomis spp species like the long-eared sunfish (Lepomis megalotis), redbreast sunfish (Lepomis auritus), and pumpkinseed (Lepomis gibbosus). These fishes will need a 100+ gal (378 L) tank as they get large and are territorial much like the larger South American cichlids. These fishes also make interesting alternatives to goldfish and koi in a pond. In clear water their beautiful colors can easily be seen, especially during spawning.

The North American fish lineup also includes some livebearers and killifish. While these aren’t the most colorful, they are still interesting to keep in aquariums nonetheless. Some of the best looking are the flagfish (Jordanella floridae), northern studfish (Fundulus catenatus), and the sailfin molly (Poecilia latipinna).

This isn't intended to be a comprehensive guide to North American natives. I just want to open your eyes with this article and let you know there are lots of choices out there. If you have a further interest in these fishes, I highly recommend joining the NANFA forum. I am aware there is a bias in the listings of fish here: they are almost all from the eastern US, but that is where I live. I am most familiar with the fish in my backyard. I encourage you to get familiar with the fish in your backyard no matter where you live. You never know what little beauties you may find!
