And yet again some of you morons keep lumping all cichlids from africa as "african cichlids" and making the same assumptions for each and every one of them. Get a clue, is it really that hard to say Malawi? hmmm nope. Of course this is comin from someone who just had to scroll down the page a bit to see how my Screen name was spelled, but instead chose to just guess.
Oscars are NOT suited for 55s, they get too large for them, how would you like to only have about 12" to turn around in when you yourself was 12"? 75s are the minimum. Sure people keep Oscars in 55s "just fine" but like it or not, its not anywhere near the best for the fish, if you can't provide a good home for the fish, tank size and all, then DON'T buy the fish.
While your maintence regime may seem impressive to you, its not. Thats about an average routine.
No one is adding suggestions, learn to read a little bit more. I see Apistos, angels, other dwarf cichlids, convicts, blood parrots, I'll take africans to mean Malawis, Tanyganikans or Victorians ( my whole point to critising that one is that not all "africans" are built to be the same size, a 55 is too small for Malawi eye biters just as an example, try puttin 4-5 of them in there), so suggestions have been made before you came along.
OH well though.
