Hi all mfk i recently purchased a reticulating stingray from my LFS $30 good deal i think . Anyhow its a young ray maby 7" from disk to tip of tail . He wont eat . I know this is a common problem with new rays. he has been in the tank for 3 days i put frozen blood worms in he goes over them but seems to just breath on them not actually cup them and eat them. Any advice will help. Since he is tiny he is in a 20L tank once he is alittle bigger i have a 125 gallon waiting for him . Tank mates are 2 baby ebjd's maby 1.5" 306 fluval filter tank is at 85 degrees all the time and water changes are done every 2-3 days . Any advice will be appreciated thanks !
