i woke up this morning and my starry blenny was covered in sand. at first i thought it was funny..hes quite the character and is always getting into stuff. but then a few minutes later i noticed he was in the corner of the tank on the bottom wiggling/twitching/itching on the sand. i didnt see any markings on him like when he got stung by the anemone. could he have ich? or am i just being paranoid?
