They will eventually be eaten by the cichlids as they grow bigger and more agile to hunt down the shrimps. I used to feed my cichlids ghost shrimps as a treat on a monthly basis before when I had ghost shrimps. As long as the cichlids' diet consist of mainly flakes, pellets, or frozen food. A shrimp for a treat once in awhile is not a bad thing.
The hard exoskeleton of a shrimp might be the only problem that I can see IMO which might cause constipation to the cichlids if consumed regularly.
