Ok, I have a quick question. My tank has been established for about 9 months and had a good community going on, but recently one of my angels have been killed. The tank I have is a 65gal angled front tank and at present has two snake skin groumies, one pearl groumie, one green severum, one bala shark, one pictus catfish,one striped angel, and one African Knife fish. I want to replace my angel that died with a Festivum cichlid maybe two and take out my other angel and put it into another tank with some other angels. But will the Festivum disrupt the community would like to know any input would be great.
