Weird bug in the tank?

[JammyBirch]

found this new thing in the tank...it looks like a rolly- poly, if anyone knows what that is...

It swims very fast, has many legs, molts and has two antennae and looks like two tails...

Not sure what it is or if it's good or bad. Been trying to get a pic all day...fast mofo...

could be a chitton, but they arent fast. could be an amphipod, but they dont look a whole lot like a roly poly.

check here, maybe you can find it:

Amphipod, more than likely. Chitons are no speed demons, and live attached to rocks...very tight clingers.

Could be an isopod. If it rolls up = good. If not, could be a parasitic one that will feed on your fish at night.
