Hey Restarted up my 75 gallon with 13 congo tetras and 2 female kribensis. Not sure what else to put in with them if anything, everything's peaceful right now. Transferred my old biological filter media (141 biochem stars) and prefilter sponges from a defunct canister filter (Marineland that ran for well over 15 years) to a new Aqua Top CF MKII Series which so far is working brilliantly though I've read some reviews of leaks as they get older. Any thoughts as to whether a group of tiger barbs might be an addition or would that be asking for the possibility of trouble?
