Dam, I was just about to panic, then I thought, wait, that is in your tank,, Not mine.
That stuff is fairly common and the bubbles are oxygen made by that scurvy, sticky algae. Hermit crabs don't lay eggs on a rock, they keep them in their shell like other crabs.
Something laid this in my tank. I'm thinking "Chicken of the Sea"
.Looks like a few fish came to check it out
Hi Al,
Do you think it could have been caused from overfeeding?
