I bought this recordia from CBA about 3 months ago and it had a small smooth blob of something next to the recordia attached to the rock. Every time I move the rock I notice that this thing will slowly move from it's orignal position just slightly. It always seems to stay next to the ricordia. In the last week the blob has formed a small opening which looks like a small spout, the same as a clam has. It has a slimy hard feel to it, not spongy. I was thinking it was some kind of sponge. Anyone know what this is?

Tagging along. I have some that look like that but are clear in and around my LR. They seem to be harmless whatever they are.

I first thought that it might be a sponge but I don't know if sponges move around once in place.

sponges might move around as they spread, (it would look like they are moving anyway. but im not sure about the spout, great pic though.

It's a type of sponge
I would venture to guess you have Florida LR?
