i used mine to grow algae.. it worked great... the the algae died and it started to smell... and the snails started to die as well.... so i used it to water the lawn... now its just sorta sitting there in the backyard...
once i get around to moving it inside (i need 4 feet of space!!!!!) it will be the new home for my sailfin pleco and seerve as a growout for 2 pbass...
i have this ^^ setup minus the knifefish in a 75. my other 75 houses more rotkeils and GTs. I was thinking about redoing one of the 75 for an african riverline setup.. or a single fw puffer..
Of the common types of cichlid setups, mbuna were one that I never got into until recently, and they are a blast, just depends on what species you like. I mix them with haps, although probably won't be for too long
