So saw this front and center on the glass this morning. It's sitting in a contain in the frag tank now - can toss it if it's a known baddie or let it grow for a little while in the container and see what the heck it turns into! I suppose it could be a tiny RBTA transfered from my Dad's tank. It seems to stick pretty quickly - I took the pictures and by the time I walked back to the frag tank to transfer it to a different container, it was sticking by the foot already. Anyway, here's the photos...
