Hello, I have a 55 gallon community tank with a few BN plecos, corycats, orange mollies and a few angelfish. Now I am thinking to add a pair or two of colorful SA or CA into the tank, and hopefully can breed them. So I prefer some colorful cichlids which are not too diffucult to breed and not too aggressive. I breed blue rams in another 29 gallon tank so would like something different. I thought discus would be a good choice but heard that they need high quality water and not very easy to breed? ALso, LFS is selling some nice red servrum but it's very pricy and I heard that they are infertile due to inline bred? I may get a pair of discus or servrum but would like to hear other options. Any suggestions would be highly appreciated! thanks!
