Dying twin spot gobi..Need help ASAP

[guinness0514]

Guys got a Twin Spot Gobi from the LFS yesterday and acclimated him and put in tank...he seemed stressed and didn't move. I checked him this morning and still not moved. he seemed to be gasping. I checked my nitrates first and they were at 5.0. I immediatedly did a 20% water change...He now is swimming around the tank and turning over like he is starting to die. EVERYTHING else in my tank is doing fine. I have two clowns that seem ok. What can I do and what do you think the issue is....Don't have long it seems..he is acting pretty bad...

HELP

Bad signs, probably not much you can do at this point. Twin spots are not the hardiest of gobies and often succumb to starvation even when eating. Yours may have been sick at the LFS and the shock of catching, transporting, acclimating, and a new environment probably put him over the edge.
