Species compatibility

I'm trying to figure out the best way to set up my tanks to accomodate all my fish. The unexpected rescue of a grass pickerel from a drying mud puddle has destroyed what was previously my community tank. Most of what was in it were fish that were acceptable for feeders anyway, and the darters got moved. However, I want my community tank back. Help me figure out how best to distribute fish among my tanks to make room. I want the community tank to contain Heterandria formosa, least killifish, Lucania goodei, bluefin killifish, Elassoma zonatum, banded pygmy sunfish, Etheostoma fusiforme, swamp darter, Fundulus chrysotus, golden topminnow, and Labidesthes sicculus, brook silverside. Wondering if bluespotted sunfish, Enneacanthus gloriosus, are compatible with that list.

Currently available are the following tanks, listed with present inhabitants:

75 gallon, filtered by a 50 gallon sump at about 400 gph. Currently housing 2 blugill, Lepomis macrochirus, 3 redbreast sunfish, Lepomis auritus, two bluespotted sunfish, one unknown shiner (about 4", plain silver, and quite peaceful but big enough not to be bothered by anybody - this was a bait bucket rescue and I have no idea of its origin as I've never seen anything similar), two mummichogs, Fundulus heter and one American eel, Anguilla rostrata, about 10 inches long. Gravel substrate with brick, rock and driftwood.

55 gallon, sand substrate with live plants. I would like this to be the community tank as it is the most suited for plants. Currently housing three juvenile bullheads from 2-3" and two fat sleepers, Dormitator maculatus.

60 gallon, gravel substrate. Inhabited by the 5 inch grass pickerel and a cloud of feeders. This is a custom tank and it's really too deep for plants.

30 gallon, crushed coral substrate, contains a marmorkrebs feeder colony and half a dozen melanistic Gambusia. I'm trying to breed these, but so far no offspring have the marbled trait. I'll soon have some females from the first wave of fry to try to breed better stock though.

I may just add a new tank, but I'd prefer to rearrange if possible. I'm thinking the sleepers and catfish may be big enough to live with the pickerel for the time being, and could be moved later. If I did that, will the bullheads compete for feeders (young Gambusia and convict cichlids, mostly)? Any other ideas on how to change my setup?

You could put the fat sleepers in with the pickerel as long as they are around 5 inches, and put the bullheads in the 75 gallon. Then you would have the 55 gallon empty. Maybe even put the shiner, mummichogs, and fundulus in the community tank and put the pickerel in with the sunfish.

The shiner and topminnows will be fine in a community tank, but mummichogs are vicious creatures, even more so than the pickerel in my experience. The sleepers are not more than 3 inches, but they might be 3 times as big around as the pickerel - overall they're much bigger.

Thanks for the reply.

The reason I haven't considered placing the pickerel with the sunfish is that the sunfish aggressively attack feeders even slightly larger than the ones the pickerel eats. I can maintain the pickerel with an expedition to catch feeders every 3 weeks or so, supplemented with baby convicts. A similar quantity of feeders placed in the sunfish tank last only about two days. I don't have time or a sufficiently sustainable collection site to handle keeping the sunfish in feeder fish. I've heard pickerel can be trained to pellets, but this one hasn't ever shown any interest, and I'm not willing to starve him. It's also interesting enough to watch him eat that I don't really want to feed train him.
