Cause for Canary Blenny problem

[think2100]

I just received a few fish from Dr. Reef yesterday. The Canary Blenny initially looked very healthy, almost immediately swimming about and eating copepods. Today I noticed him pressing up against a rock (see photo), and then saw that part of his underside seems to be missing (see photos). There are no aggressive fish or corals in the tank. Other fish are a firefish, red stoplight cardinalfish, and a small tailspot blenny. Thoughts on causes?

This fish is extremely thin. Has it eaten at all?

Yes, been eating copepods, reef jerky and nori, until this afternoon. Is the collapsed underside just “thin”? It looks like a missing piece of him to me, white color in contrast to otherwise yellow hue.

The diet is insufficient. Add mysis shrimp, plankton and even LRS fish frenzy. Yes fish has that shape from being so skinny and im hoping its not edema in which these fish can shut down with feeding and feed off its liver

It is pretty thin. Do you know the salinity it was shipped in versus your tank? It may be dehydrated from a salinity rise.

Here is an article on thin blennies:

Skinny Blenny issue

Skinny blennies: Midas blennies are much more difficult to maintain than their common presence in the pet trade would have you believe. They are very prone to starvation. It is unknown if this is due to not feeding them often enough, not feeding enough, feeding the wrong foods, or if internal...

Fed mysis as well, but it has withdrawn completely now. Don’t expect it to make it through the night.

Unfortunately I think its been feeding off its liver. Sorry to see

Shipped at 1.025 and placed in 1.024.

Likely not significant enough to cause this

That rules out salinity rise as a cause of rapid emaciation.

How does it look today?

All I can suggest is to feed multiple times a day as much as it will consume at each feeding.

You might want to contact Dr. Reef, they are very responsive and may have some other advice.
