My long fin seemed weak. But I think he is just messing around. This morning I saw my canister filter was closed so I opened it up. Did two <25 percent water changes (so about 5 gallons out of my 15 gal) because it must’ve been maybe a couple days since I last fed him with the filter being off. I have only done this once and that was during my first month of saltwater so I always had a system to make sure this never happened. He was just laying on the sand bed and wouldn’t eat. As soon as I started typing this he swam out and chased my damsel. Salinity is 1.025. Ammonia is little to none. Using API and I should have asked for Hanna ammonia checkers I just realized. He is swimming in and out of the cave now and looking like he woke up so. I think I’m gonna make fish sticks if he keeps on playing dead
