I've had this thing for about 2 months now. I know they require slightly deep sand beds, mine ranges probably from 2.5 - 3 inches, depending on where my eel likes to pile it up, or some crabs rearranging. Anyway, this thing will not attach. I have tried just letting it do its thing, always ends up getting blown near the glass and won't attach. I have tried barricading it into the sand/rocks, digging out a hole for it to anchor to the glass underneath, etc. Tried turning off the powerheads, no go. It looks healthy, the foot is sticky as it picks up sand and whatever else it touches, it opens fully, and also will eat anything that it comes in contact with. My rainbow bubble tip is attached, all coral is wide open and happy, just can't get the anemone to stop blowing around like a crazy tumbleweed. Any thoughts? Thank you!
