What is this little thing?

[forrealb50]

I looked at all the hitch hiker ID thread and can't ID this little thing.

I think he has 4 legs on each side with a hard outer shell. It looks just like a "roli poli". He crawls around just like one too but doesn't roll up in a little ball.

You haven't provided any idea of size/scale. How long is it?
Could be an isopod. Not necessarily a good thing….

Sphaeromatid isopod, harmless micrograzer & fish food.

+1 for isopod. Does look like the harmless one luckily. I had the bad ones when I setup my 2nd and current tank. Took a lot of work to get rid of them.

I just did the research on ispods. They are 100% isopods. Thanks for all the help.
