Not sure if this has been discussed. I would love to have a cool crew of shrimps in my 50g frag tank. My display has way too many wrasses that will probably eat any shrimp i put in there. My questions is would there be any compatibility issues? I was thinking about adding a couple aiptasia eating peppermints, Fire shrimp, and a pair of Sexy shrimps and maybe a arrow crab. Tank is a 50g low boy frag tank and will not have fish in it only snails.
