giar, I think we touched on this on one of your other threads, but the issue you are going to have starting now, is maintaining proper water parameters with these fish in this small amount of water. Assuming this tank is properly cycled and producing nothing but nitrates, your nitrate creep is probably going to be more than 5ppm per day. This is going to mean you'll have to do more than one fin-level water change per week to keep nitrates under ~20ppm.
