Just checking something - if I have adult corys is it ok to add in juvies - the juvies are only about 3 or 4 cms - very cute but just wondered if the adults would bully the little ones
It depends. Some adults can be pretty rough. I don't know about bullying, but most Corys run over anything in their way, kind of like a litter of puppies. I have seen some make it fine with the adults and others not so good. In general I wait until they are a bit bulkier and about an inch WT. Although I just dumped a net of aeneus fry in the adult tank. Juvies also require better water conditions than adults.
