Hermit crabs eating bubble algae?

[JayM]

I noticed a thumbnail sized patch of what I believed to be bubble algae last night. I grabbed my siphon tubing and some tweezers to get it out this morning, but it was gone. In its place was a couple of my red legged hermits. Did I just get lucky, or is this a normal hermit behavior?

A lot of hermits will just about any kind of algae they come across. I prefer the larger thin stripe hermits as they have bigger appetites and will go after stuff tiney hermits like blue leg and scarlet are too small to be effective.

Mine have never touched my BTA.
