I just noticed these today, the tank is about 2 months old you can see them beside the thermometer. I haven't seen these ever before.

Sorry for the picture, its an iphone :( best I can do.

thinking maybe Munnid Isopods

Isopods

Very beneficial little buggers. Great fish food as well. That's part of mandarin fish diet and many pod eaters.

Thanks for the info :D I noticed them on the glass all over at least any place that had some algea growth.

Glad they make great mandarin food since I will be in the market for one in another few months.
