However, aren't there any smaller fish such as minnows or small sunfish that could be kept like North American versions of danios and cichlids? I think it would be really cool to have a local biotope with some of these fish represented.
How would I go about keeping such an aquarium? Would the fish require a heater for part of the year and a chiller for winter? Or would ambient room temperatures work fine? Could wild-caught specimens be fed on prepared foods, or would they need live food diets? I suppose much would depend on the species I'm interested in, but since I don't know much about local fish, I could be educated there, too. Anyone who knows anything about Mid Atlantic area freshwater fish that would be suitable for a smallish aquarium (55 gallons or under for now) would be a big help.
I'd think you might need a brackish setup for chesapeake-bay based species.
Also, when pulling from the wild (with which I don't exactly agree), as opposed to captive-bred species; evolution says they tend to be much more tempermental to the enviroment from which they came. So, you'd need to extensively test the area from which the fish came, and do your best at replicating those conditions. I can imagine it would be easy to overly saturate the water with harmful chemicals that would only show up in a concentration-type test and might not show up in the simple "balance" tests that just compares levels of " opposite
" chemicals -- ions, acids, bases, carbonates, etc.
I know the Chesapeake tends to have a very fine silt floor/substrate, slightly salty (not sure on the specific gravity), marshes and lots of sunken local tree species, tires and industrial waste as you approach baltimore
**** note***** I'm new to aquariums, but I've lived near the bay all of my life.
