if you mean the neon goby hes actually a tank bred specimen...haven't heard anyone having much problems with keeping them alive in the aquarium.i wish local fish stores stopped selling this fish because of its low price and high mortality rate. 1;100 survive in captivity. a fish best left in the ocean. i too have tried this fish before learning about its poor success. hopefully all goes well with your because they are an interesting fish to watch, ;ove hoe they sleep in the rocks![]()
