Not really in cherry grove, but i would say less than 5 to 10 miles away is Sea Critters Depot, and they have a very good variety. Not sure what his friday hours are but I know hes open saturday and til 6 on Sunday. If you wanna travel a bit more there are a few in surfside... Coastline, The Reef Shop, and Exotic Fish South. If you have any more questions Im sure any of us can answer them!
