Unfortunately this case is now closed; i discovered my jawfish's body under my aquarium stand, disguised as dust bunnies. I dont know how he got out, my tank is well sealed so i assume he jumped out during a water change and slipped by me unnoticed. I am a little relieved to have this closure, and also to know that he didnt die of water quality or disease, that being said, RIP El Chapo, you were my favorite fish and will be missed.
