I think they would be ok as long add the shrimp are bigger than the gobies they will eat anything they can fit in their mouths but they stay small I like they max at 2 1/2 inches. The guy I bought mine from said they bred in un heated un filtered 2 gallon tank and ate flake food. I keep mine in a planted 65 and feed them blood worm and black worms. About 74 degrees
