Is that parasite or itch?

[Notsolostfish]

I tried to get a video and the blenny is fast to hide and i couldnt get it. Im new to the hobby and i introduced a bicolor blenny yesterday. And the thing is i did it without QT. Hes eating no issues. Just seen him like zooms on rocks kinda like flushing or scratching i dont know if thats the case or not or thats their behavior

Sounds like 'flashing,' which can be from a parasite like ich.

Might not be though. I would keep an eye on it.

If he eats, let him be.
If he stops, then, maybe.

how many other fish do you have? I had a firefish start flashing just a day or so after adding him and knocked out my other 2 fish with him
