Midas Blenny Eating but very thin.

[JATReef]

Hi guys, just wondering if anyone had any tips /experience with this.
I have had my Midas Blenny for about 6 months, no issues whatsoever. However recently he has become very thin, to the point he looks sick. His behaviour has not changed at all, constantly swimming around in the water column and perching on rocks.
I feed a mix of live brine, frozen mysis, pellet and flake food and readily eats all of these food types.
Any ideas on what could be the problem would be greatly appreciated!

How often do you feed? Did you ever treat him internal parasites?

OP,

How's your Midas Blenny doing? I had mine since March 2019, and have the same issue as getting thinner, but still active. It doesn't looked stress to me.

I feed New Spectrum with garlic pellets daily once using an auto feeder. Every two days, Hikari Mega Marine (half a cube). Also Seaweed hanging daily.

It seems to be a picky eater, as I've noticed mine doesn't go after the dispensed pellets floating on the water, and will only take in the smaller chunks from the Hikari Mega Marine. Also, sometimes, would spit it out.

I also need some advice on how to fatten this little guy up. He is with a clown fish, blue tang, and sixline wrasse. They seem to be happy together.
