Not necessarily. It's just that many hardcore Mbuna keepers frown on these kind because they dilute the genes of purebreds. They're concerned that when they breed, you'll sell the fry as a certain species, which would further dilute the gene pool.nitrofish1;5106412; said:but the consensus is to stay away from the mixed or "assorted" batch? even with a 55g?
I would say just buy whatever appeals to you. Unless you get setup a species-specific tank, these fish will end up crossbreeding and you'll end up with some hybrids anyway.
