Hi. Right now i am having a 2,5 cm long leopard cteno. I want to put something nice for a bottom fish and something herbivore. Should i put 3 sterba cory since they are a bigger species of cory or a red fin shark since both of them are kinda passive aggresive fish? Or is it more suitable if i put boosemani rainbow or 3 congo tetra that are around 3 cm long with my cteno? My original planning is to put my cteno with an african butrerfly fish and a peter elephantnose fish to make somekind of african oddball tank. Should i be patient and stick to my original plan or maybe i can pick something from the fish forementioned above because my cteno is still in manageable size and they can grow together? Thanks and sorry for my terrible english
