Hello. I’ve had a QT set up for 3-4 weeks with a piece of live rock and bunch of PVC. This translucent thing popped up from who knows where this weekend on the glass. First I thought it was a slug or a snail in search for a shell (since I’ve had cerith(?) babies appear in the last week for so. But then I piped some mysis and spirulina to feed the fish and then it turned into some tree-like shape. Anyone know what is this?
