something on my hermit crab

[appleajax]

I saw this when I was floating the hermit's bag in my tank.. I didn't really think too much of it but I was just wondering what it was.

 

the hermit crab is about one inch long so you can kinda tell how big that thing is

 

this is the zoomed in shot:

harmless featherduster.

 

I have a red duster on one of my hermits.

can featherdusters reproduce quickly? because I think I saw another one just like it in my sand

They can reproduce fairly quickly, but not like something that will take over your tank. They stay very small. It's cool that one ended up on a shell! They're filter feeders - will just eat whatever stuff is floating in the water. But if you get interested in them and want to get some bigger ones (very pretty) they do well with additions of refrigerated phytoplankton.

sweet, they're awesome

 

I found another one of my hermits with two featherdusters
