I'm gutted. Came home to find my 3ft+ AUL dead. There's no reason for it's death. Tank is a 300gal with a trop gar as a tankmate. Temp is 81.4F. Ammonia 0, Nitrate trace. <10ppm, nitrite 0. Substrate pea gravel and aragonite. pH 8.0.
Did a routine weekly 50% water change last Thursday. Checked the FX5 canister and only the bottom pads needed to be cleaned off. Replaced 6 bags of large Chemi-Pure in the FX5. Ouflow hits the water from a 1/2" above the tank surface and flushes water through 10lbs of sintered glass cylingers in a wide mesh net bag.
Yesterday's feeding consisted of live earthworms, a couple of raw market shrimp, and Ken's sinking mixed sticks. The gar ate these too and is fine. Worms are from my breeding bed and all the fish feed from these worms. Shrimp bag is half empty with no problems in the other tanks form the shrimp. Sticks are fed to all tanks, too.
No chemicals used near the tanks. No oven cleaning recently. Softscrub was used in the master bathroom 3 days ago but, that's 50ft away and the door is kept closed to keep the cats out.
The other tanks in the house are fine. Everyone is behaving and feeding normally. I can't see what may have caused this.
