dude, if your gonna go with anything i second(or third) the yellow lab african, they are a whole different aggression scale, they actually might pick on you FH, i have a couple in my SA tank with breeding RD, seriously , the bigger S cichlid like have respect for em, and even if they wanted to eat em , they'd have to catch em first...have you ever tried to catch one of those little b**tards in a 200+G tank? the only thing is that the PH levels are different but mine dont seem to have a problem in low PH. id just get like 2 if any ... good luck!!!!
