The discus that I'm going for would be older juviniles around 4-5" Again I will put this link up to show what I'm trying to get close to
http://www.nobobo.com/ Great site, cool plants, and a setup that looks like all of the fish are happy. . .The number of fish I'm going for in my 125 is x4-6 discus/x25-35 rummynoses/x15-20 corys(to clean up what the others missed)/x10 hatchets/x3rainbows/x10-15 cardinals (if that is too much tell me) and also, can some species of large cleaner shrimp work well in the tank as a cleaner crew or will they just be another snack?
