Caught this sucker alive: is this an isopod?

[SimplyVibing]

My LFS told me that I had an isopod in my tank based on a video I showed them. I think this is the same critter, can you tell me what this is?

*IMPORTANT EDIT* and if it IS, could there be more?????

Yes, amphipod are great clean up crew. I have a ton of them in my system. Fish love eating them too!

I'll be honest, they really freaked me out at first. I thought it was creepy like having roaches. Now I add them every chance I can.
