So the fish basicly whent on a hunger strike and sulked until it got what it wanted. LOL....freakin fish brat! Now, one up it, stuff the shrimp with some high quality pellets to make sure it gets all the nutriants it needs a stright shrimp diet wouln't be good for it long term. Start with one pellet and slowly add more till it either rejects the shrimp are accepts the pellets. If it rejects the shrimp back off on the number of pellets and slowly ween it onto them, you get the idea. Good luck I'm glad it's eating.
