That's what I was thinking and hoping but I don't know how they got in the tank. Frag tank and everything has been dipped in BAYER. There are several in the tank, only noticed in the back so far but im sure they will make it to the main tank soon enough. Still haven't introduced pods to this tank yet but plan to soon.
Don't worry harmless algae grazer. They are very hardy so I wouldn't be surprised if they hunkered down, sealed their shell and made it through the dip.
