I am watching my friends 1/2" NGT while he is out of town for three weeks and I forgot to ask him what he was feeding it.. what should I feed it he has accepted some wardley spectra max tropical flakes but not that much what should I feed him??? he chased the fullgrown male betta out of his tank I found it dead next to his tank weird I thought.... but ohwell.... he was in a 29 by himself I have him in a 5 now by himself but he was with the male crowntail betta....
