So I'm moving my tropical fish into the 25 gallon vacated by the goldfish. The goldfish tank has a HOB filter and a canister and a small powerhead. Should I still use all three of those things for the tropical fish? Will cories, mollies and a betta like some current in their tank? Hate it? Also, I could remove the canister and use two HOB filters instead. What do you think?
