I recently purchased a Indo Pectina from frags2fishs. After a good coral Rx dip he was placed in tank. After a day or two of observation I noticed this small part of the Pectina where the skeleton is showing. And I believe there is a pest but I’m not sure can someone give me some insight
looks like aiptasia, if youre worried about pest/parasites you need to have a quarantine tank and dip for a few weeks. Dipping once might help but wont kill eggs.
