I have kept all kinds of cats but never knew about these guys till I came across that post on PC. It seems though the tolerate and actually prefer cooler temps which is different for me since my 183's are kept at 82. From what I have found there really is no trick to these guys spawning just patience Abd a good feeding routine.
Do you have any idea at about what size/age the males start to show their coloration and what the max size is? I have read up to two years and from 3"-4".
