Your fish are more tolerant than mine..my angels and kribs took turns harrassing each other to the point my angels were tatterred too often and the kribs were angry all the time. Rehomed the kribs (p. Pulcher) for peace, then made mistake of bringing red jewel cichlids home. Have four tankfuls of them (jewels) now..Bright red, and wild as all gettout!.. You are welcome to the r. jewels..I think about an inch long is good shipping size, but I have smaller. Interested?
