well they will need to be in seperate tanks all together and only put in the same tank for spawning purposes, she will need to be in a net trap, glass funnel or simular to condition up whilst in the male tank so that he cant get to her but can see her, when she is in her own tank first, you can feed her 3 x a day on live or other high protien foods to get her conditioned up and finish this when she is in the male tank in her secure compound. this should take 2 weeks to do before she is ready for the male, when she is mega fat with eggs and displaying vertical stripes and with him atleast building a small nest you should be ready to let her go to swim around with him,
