TIGRINUS DEAD =-(

  • We are currently upgrading MFK. thanks! -neo
There are several rivers in Peru with the Nanay and the Amazon probably the 2 most prominent ones. The Nanay has very soft water and is rletaively slow moving. The amazon river has strong fast flowing current. Most, if not all, the big Catfishes we get come from the Amazon river (Tigrinnus, Goslinia, Vaillanti, etc). So even though you are thinking of the Amazon river in general, Raul is actually being specific because he means they ocurr in the Amazon river in Peru, not in the other rivers that we also get fishes from.

. 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.

Jarret...bingo

You are correct my friend. With the two net cages I have in my tank, two outputs are faced downward under the water for current to be directed to the net cages. This leaves only two outputs breaking the surface of the water. In addition, I am reducing the water level in my sump so that there is an increase of water to hit the air before the water. I am setting up an additional 125 as a holding tank so that my sump will purposly be used as a sump oppose to an extra holding tank =-)

Can you take closer pictures of your sump and send them to me.

Thanks bro....

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.

Jed,

The TIGS had the bumps when they were alive not when they died. My 3rd Tig is completly fine now w/the swelling gone.

They are abundant in the cataracts of the amazon..if im not mistaken its called the teutonic. An area of the amazon that has very fast moving current.

I was also being lazy when i mentioned high temps without explaining the correlation bet high temperature and low oxygen levels.

The "bloat" or "hump" could have occured post mortem.. or did R1 mention the tig having a hump just before it died? There you go, im too lazy to go back and read the post again. :shakehead
