So sad to share but last night I lost my fist fish. It was a clownfish and he had been with me for about three weeks. I noticed he started swimming odd like vertical which I thought was a bladder issue so I stop feeding them and it got better. Then a day went by and his swimming declined again. Anyone have any good recommendations on how to heal a sick fish? I want to get stuff on standby as I am not a fan of losing fish.
