Additional comments: These fish are quite hardy and have been breeding like clockwork with large numbers of fry. This latest batch of fry are enjoying their new abode using “Dean’s Fry System”. It is very convenient for feeding the fry and for keeping track of their growth. The fry are kept with the overhead lights off, so they only receive indirect lighting from nearby tanks. Also they have a little guppy grass for cover and to provide some biofilm/nutrients.
