Diamond goby not looking good!

[Saltwaterrube]

Hello all,

I 'm fairly new to the hobby. I have a 90 gal, fish only tank. All the water parameters are fine. I have 2 clowns, 3 chromies, a blue damsel, a big eyed squirrel fish, hermit crabs and a decorator crab. I've been feeding them all mysis and brine. He was just fine last night and now he looks pretty bad. Any thoughts??? Thanks.

Looks like an infection. Any way you could catch it and treat it in a hospital tank? From the look of your sand, your tank is on the new side. Diamond Gobies (and all sand-sifting Gobies) need a large, established sandbed to sift through all day. This needs to be the majority of their diet, with supplemental feedings. Not sure if this is the direct cause or not, but I am sure it won't help. If he does pass, I would not add another until the tank is well established. Feel free to update with its status either way!
