Midas blenny strange behaviour

[Moraal]

This is my first post.
Ive had a Midas blenny in my observation tank for almost 3 weeks. He looks great with no signs of illness. But he acts strange. He will swim around normally and then dive down and rub the sand, occasionally picking some up and spitting it out in the water column. I fed them mysis shrimp this morning and like normal he gobbled up as mush as he could. I then noticed that he basically puked some back up. I don’t know if this is normal blenny behavior but thought I would run it by everyone. I tested the water last night and it’s amm 0, nitrite 0, nitrate 5-10 using API. I have 5 gallons of salt ready to do a water change tonight. It’s a 25 bow front.

Update: this morning he didn’t eat at all. Found him sleeping in a cave on the sand with a fire fish. Came out for the food but didn’t eat anything. Then went back in. I notice is mouth is slightly open.

Any update on the Midas?

Unfortunately he died the next day. I drove 300km each way to get medication for him and he died while I was gone. At least I have it now, and am prepared. Still don’t know what it was. I had fire fish in quarantine with it and they started flashing and rubbing as well. I went hypo salinity and they seem 100% better.
