Ok, this is coming together in my head now. I'm thinking start off with 50 mudminnows, allow them to create one batch of F2 minnows. Then stock two 3" walleye fingerlings. Leave for 6 months to one year, then think about adding 2 or 3 black, brown, or yellow bullhead. Is this sound?

As for the mechanical side of it all, the filtration issue should be easily solved with some canister filters and power heads. Is it better to have one, very powerful canister filter, or a few smaller ones to handle the job? And as for lighting, I would like to find some native plants used to growing in 6-12 feet of water, and just use some very weak flourescent bulbs. Maybe some coontails would work.

Thinking ahead now, would 260 gallons with more than sufficient filtration be able to handle a possible 2*5pounds walleye scenario? Jeeze, this is exciting!
