Hi. So I had this scoly for about almost a month now and it’s been doing pretty good until now. My tank is still relatively new meaning I started it in July. It’s going through the ugly phase now with diatoms and green algae. But I noticed the scoly has a small patch of skeleton showing. Literally 1-2 days ago it was fine but I have noticed my red legged hermit crab would hang around it/be on top. It are the smal patch of I think hair algae on the base but it’ll still walk on top of it. My parameters are ok I need to buy a ca,mag, and phos test. Which I will get tomorrow. Could the culprit be the hermit of just my “new” tank?
