Tomoko Heres a twist for you. I dont use Neons at all, but i use alot of Cardinals.... they do better and look better without the Neon disease.... havent had any problems with the group of 7 adult Cardinals in my 55 gallon tank that houses my breeder group of Apistogramma Elizabethae. Everyone does well, each keeps in their own zone, cardinals up top, apistos down low... peace and harmony.... i also use glow light tetras too..... they stay small and dont seem interested in the apistos or their fry....
