So scooter not sure what he is is a watchman either blenny or goby can't remember which I saw him earlyier and he was looking a little spotty. I looked for him two hours later and found him barely alive but being eaten by crabs I tried to stop them but he is dying. Everything is fine with our water and all other fish look great. It wasn't white spot looked kinda like grey spots or something all over him. Do ou think my other fish are fine
