Naw, man. Just show up and pay your $5.

I'm not really into cichlids, but there sure seem to be plenty of them. generally I just skip over the tables that are solely cichlids (except for angels) and there are several of them. I'd guess at least 10-15 on an average show, each of which had many many fish.

Whether they have exactly what you want depends on how specific your needs/wants. But when I was considering "some kind of" apisto, there were several different vendors who had various stock, were able and willing to discuss things in detail with a neophyte, and had numerous inexpensive fish to suit my needs.

if you have very specific needs, it might pay to get there early.
