TIGRINUS DEAD =-(

  • We are currently upgrading MFK. thanks! -neo
Delgado,

I agree with the others, I too think it is from lack of O2. the bump wasn't caused from lack of O2 but like alfon said it could have happened after death. Possbily a sort of bloating like most dead bodies do after death. Since the heat is the trigger decomposition is sped up in the prcoess.

Even if the river has the same temperature as a tank it doesn't mean that the amount of disolved oxygen is the same. Tige come from fast moving waters with lots of turbulence and that helps increase the disolved oxyegn in the water.

Sorry but I agree with armac on this one. Before you give firm wrong advices please do a bit more research first.
 
Joey, the only thing that doesn't make sense is that you are pumping around 6000gph in your 600 gallon tank. Even at those high temps. with that much flow, you should have had plenty of oxygen in the tank. I have been to your house and seen your tank, you have lots of water flow. The only thing I can think of is that most of your outputs if not all of them are under the surface of the water, thus reducing the amount of disolved oxygen. If you raised all of your outputs to your tank above the water level so the water splashes on top of the surface like a waterfall, this would greatly increase the disolved oxygen level in your water. Also, your returns go underwater in your sump and are not creating much oxygen in the water vs a wet dry system where the water trickles over a media causing alot of oxygen in the water. These are just ideas, but one would think with that much water flow and turn over rate, you would'nt have an oxygen depletion problem. Glad to hear bullseye is doing better. Hope he pulls through. Take it easy.

ps. I wouldn't rule out beefheart as a possible cause. Vince has been misteriously losing chinese perch. I think he had 5 total and I bought one from him from the same batch. He fed his alot of beefheart and I feed mine shrimp and smelt. He has lost 4 and mine is doing great. We talked it through with eachother and came to the conclusion that the beefheart was the only diff. factor between our fish. Since then, he has been feeding his shrimp and smelt and his last Chinese perch is doing great. This may have nothing to do with your tigs. death, but it is something to think about.

The only thing wrong with that theory is that Joey said that his last one that is still alive has the bumps on his head too, just not as bad as the one's that died. I think if the fish's organs started to shut down like a kidney, then it would cause that bloating too.
