Really? So they are fine as being solo fish?Heckelii are my favorite fish by far. Trying to select which 4 to rehome of the 7 I have is proving difficult. I've read and been told they do fine in groups until around the 3 yr mark or so which is when conspecific aggression seems to kick in and they get brutal. A fw folks have reported having a juvie group grow out well together but I think that is more the exception than the norm.
