Why not, rather than waste them, I've eaten many cichlids even those I've kept when in the states.
If they've been mortally wounded in a fight, or mishap, rather than just throw them in the trash, or prolong a lengthy death in a tank, I'll give then a quick death, and sauté a couple fillets up.
Feed any left over bits to the remaining tank residents, and compost the rest.

My neighbors prefer needle fish, and sell other fish like red snapper to us gringos..
