Quick question, how do you breed Rummy Nose Tetras? I have 4 at the moment and may be getting more. How do you tell their genders? i want to breed them but don't know where to start. Is there any specific needs that the tetras will need in order to breed? I also have 2 albino corys, 4 mollys, 2 dwarf gouramis and the 4 rummy nose tetras. They are in a 70L tank which is moderatly planted.
