I dont have cichlids, but i can give advice, as long as you are super sure, that there wass no poison used at all to kill them at any point at all, or any chemical at all, and as long as you find them away from a polluted area, then i would think so, my gourami snacks on misquitos that just fall in, and i hope they are safe, im gonna have to block my tank cuz i ddont want my fish to get AIDS! ;-)
