Bta speckled foot

[Goaway]

Now, this sounds weird and looks weird. I never seen my rainbow bubble tips foot. Its heavily speckled. I did have a green bta once. It just had a red foot.

For this one, it does not roam. Has been on that very rock for a month. That very shard. I had to remove him out of the aquarium with his rock to remove a eunice worm.

I chistled the bta off and placed it back into his original spot. This was probably 2 weeks ago.

Just recently the bta has been standing up and revealed his foot. I never seen this before.

Lighting? I dialed back my kessils and it caused my nems to reach more than they used to. Maybe just adjusted to your lighting and wants more?

Full daylight
Last Wednesday

Only today, was the first day it stood up like that. Usually. He's been lazy.

I suspect that it'll move soon. They typically don't like to have their foot exposed like that, but rather buried in a crevice. That said, many BTAs have a "mind" of their own and oftentimes do strange things.

Also, a marbled foot on a rainbow is fairly common, and nothing to worry about (not that you were worried!).

Ty for the response. I've had this bta for a month in a half+. Fortunately, hasn't roamed 1 inch off of that rock. I'm not kidding, stayed put even after I had to chistle him off.

Just worried actually seeing the foot. To top that off, the random speckles.
A relief. Ty
Edit: I'm just going to think he has an identity issue and likes to pretends to be a toadstool coral.
