If go with the 60 gallon tank with 850 gph filtration, what can I squeeze in it. I like severums and I'd like to get 2 in there. I also like the firemouth and salvini and I'd like to put one of each of those in there too. Could I squeeze another in there, maybe one convict or something like that? Let me know what you think would be the max on south american/central american cichlids in a 60 (48X13X24). I'm not keen on dither fish either, unless they help the cichlids in some way.
