Pests, Hitchhikers, and Diseases
We got home from a few days away and saw this odd red blob growing on our live rock. Any idea what this is? Is it red slime? Not sure what's up with the bubbles??
We have two hermit crab, trochus snail, cerrith snails, and a tuxedo urchin... I don't suppose any of them would eat that, would they!?
