I'm hoping Harry is ok, but he has tucked himself up in the rocks lately and I just noticed this white patch on his...hip? Or shoulder? Any thoughts...?
(Also hoping the green on the rocks around him is coraline algae starting to take hold. Tank is about 10 weeks old with Purple Helix added week 5 or so.)
