Ita best to keep them in a group but if you're only having two then it's probably better to have one of each. Females have 9-12 dorsal fin rays (spines), males have 12-14.Ok - good to know, thank you. I may have to look at finding it a friend! Is it better to have the same sex or one of each?
How easy is it to identify between males and females?
They don't usually touch dried foods,
and are much better on meaty foods such as frozen foods, and small worms and prawns etc.
