lawnmower blenny acting strange

[oyf709]

Need to see if anyone else seen blenny acting like this before.

I got one from Canada Corals couple days ago along with few bangaii.
The bangaii are eating great and not shy to come out to open water .

The blenny on the other hand has been doing something strange lately. It would swim near the side glass and just keep flowing in mid water column. Sometime it will turn around try to bite something off its tail. It would also twisting and flow vertically up and down the water.

It also not scare of me, when I do target feeding..it will swim to my hand and sit just next to the power head which right next to where my hand is. It almost felt like it wants me to pet it.


I have seen blenny doing scratching before but never seen it doing twisting or biting its tail...
everything else seems normal, it is eating the algae on the LR and going back to its hole when my hand is not in the water.

I also don't see any visible ich or any white dots in that matter.
