My Discus - My favourite three discus swimming in order (from left: yellow male pigeon blood, red female pigeon blood, turquoise discus). The Turquoise is the biggest of the trio measuring at more than 4' and he was the very first discus I had. The pigeon blood pair are really a working pair. They had bred in my densely planted tank on numerous ocassions, and the mother had successfully raised a few batches of fries. I had since sold off the pair after the Turquoise died.
