They sound like malawi cichlids, but you shouldn't buy them. Assorted cichlids means you won't know what they are - they might be pure cichlids, they might be hybrids. What's wrong with that ?- well any that you breed you won't be able to sell, but that will be the least of your problems. Hybrids are weaker usually than purebreds, they are often hyperaggressive and are just a p.i.t.a. Also malawi cichlids have varying levels of aggression , and not all mix well at all (even within just mbuna) - putting 2 (even 1)melanochromis in any tank less than 100 gallons is asking for fish death, but you won't know it, because who knows what you've got.
Malawis are beautiful, interesting fish, and I love mine. But I would never buy 'asst malawi' I couldn't id 100% - every time I've seen them for sale they've always been someone elses rubbish - lots of big, hyperaggressive males, unpopular species, poor condition and too many hybrids. Why buy rubbish - there are plenty of good quality fish for sale that will prove much easier to keep very quickly.
Having said that there's a shop locally that had an 8 inch frontosa in with misc S Am cichlids!
