WOW awesome fish so sad you went threw that. Keep doing research bro don’t give up these are things that the fish hobbits go threw and yes it’s expensive and Achilles tangs are very hard fish to keep. Very hardy fish. So sorry you lost puma. Thank you for sharing with us. Gbless crazy thumps👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
I lost a few tangs recently. I installed a 55w aqua medic UV after removing a chronically ill fish, and now the tangs are doing well. The new tangs got a few spots but this time it went away. I no longer second guess the UV issue. Its working.
