Hello i have a 75 gallon been running for a couple years now i currently have 1 large Tinfoil barb, 2 keyhole cichlids a breeding pair, 1 angel fish Med size, and i have 2 female jewel cichlds which 1 i very peaceful and the other i have in a ten gallon separate, I am trying to breed my jewel cichlids and I am going to pick up a male soon and was curious if i could have the male and female in the 75 until they decided to breed and switch them to the ten gallon to curb aggression to the other fish mostly the angel as i view it as being defense less against cichlids, Should i maybe get another angel so if there is any agression its not targeted but i do enjoy it being the only angel in the tank right now. also since i plan on breeding, i plan on using the ten gallon as my tank to raise fry what kind of sponge material can i place around the fliters so the babies dont get sucked in ? also any other tips for inducing breeding would be apprciated.f
