in the last couple days ive lost a jaguar cat, cory, and a couple other bottom feeders. The temps have been around 82 because of the heat. All my other perameters have been fine. Everything is solid. My tank has been set up for over three years. The only difference is that I have been feeding some frozen brine I have had in my freezer for a about a month. I have been doing my regular wc's once a week. I am running around 1000 gph of canister filtration and always have air bubbles running for good aeration because of the higher than usual temps. I always run bubbles no matter waht the temps as I killed almost my entire stock last year. All the fish apear to be healthy and eating and the jag was eating yesterday. Severums, geos, bgk at 10 inches, 5" uarus(spawning). I watch my tank daily obviously because its in my living room and have not seen any aggresion other than the uarus being territorial. Anybody think the uarus are going after slower fish and killing them? Maye the brine shrimp has gone bad? all the other stock has eaten it and been fine.....m at a loss! any ideas?
