I am looking to recreate a local stream with a 55 gallon tank. Well, at least a small sliver of it.
I have the tank set up with a 1/10 hp chiller, a river manifold and two hang on filters. I already have a couple fish in there (johnny and blackside darter). The first round didn't go super well as I lost 6 of 9 (lost 3 fantains, 1 johnny and 2 blackside). At the time I didn't have a chiller. I'm hoping the chiller will help the next try.
All of the darters stay near the bottom hanging out in the small stone.
After I try adding some more darters, with the hopes the chiller will help them out (currently set to 62 degrees), what species might I want to go with to occupy the top half of the tank?
I do want to stay mostly true to the creek (Otter Creek; https://blogs.extens...Summer-2006.pdf ) so maybe the midminnow? Or at least other creeks near me which is just NW of Madison, WI...
Would love to put a brook trout in there but figure the 55 gallons is too small and he would likely eat the rest of the fish in there...
Any specific and general advice would be great!
