I work at a petco and we have assorted cichlids but it is a rare occasion that I pull deads. they also come assorted in one bag. there's usually some pure fish but mostly hybrids. we also get them in two different sizes and the bigger ones seem do do just fine with each other. I guess it's like getting a mystery bag from the dollar general toy isle. it could just end up dissapointing but you might find something cool.
