TIGRINUS DEAD =-(

  • We are currently upgrading MFK. thanks! -neo
i doubt it was temeprature

HIGHLY doubt


those fish should be able to handle a temperature of that level for a short period of time

if in fact your tig died from lack of O2 then your other fish should have died as well such as the ATFs. but this isnt the case.

tigs dont need THAT much oxygen in there water, they have the same o2 requirements as most other south american river fish that we keep.

Tigs come from fast moving, highly oxygenated water, you are completely wrong:grinyes:
 
I know ooops...:screwy: My fault.

My mind was just racing 100 miles an hour to see my TIGS start to drop one by one =-(


Of course maybe that sounded a little insensitive to your loss - Im sorry to see & hear of your loss with those beautiful Tigs - and I understand your mind is in a fog regarding the details
 
I have to agree with the others in that you cannot generalize with amazon fishes. Tigrinnus do come from fast moving waters and their temps, although warm, get regulated from this constant influx of new water. I am sure there are some Tigrinnus found in slower waters but generally they are known from rapids and even waterfalls and stuff. A constant high temp with low dissolved O2 can definitely cause damage to thye organs and gills of fishes.

Like I said initially, I am not 100% sure about my diagnosis but I was merely mentioning possibilities. If you do water changes now and notice the Tigrinnus is doing good, then you might have found the problem. I sure hope the rest of your Tigrinnus fare well and that you never again have to experience anything like this.

I have several tanks (#8 50gal-300gal) outside in s. fl. The temp has been consistantly 88-92 degrees for the past 8 wks. The tanks have excellent & multiple filtration, bimonthly 30% RO water changes. Partial list of fish; scats,monos,archers,frt; 24" aus lf,8"lechardti, clown loaches, chelsus,knife; 20"aba; 6x8" tigrenis, another 8"lechardti, af lf; 10" mbu, 250 cardinals. Don't know what to tell you but in 35 yrs of fish and other creature keeping I've lost many a creature from unexplained deaths. "If I had a penny.......

Well my 3rd Tig "Bullsyeye" seems to be doing good. The swelling has dramatically decreased. Since the constant water change and extra Rio 2500 pump inside the tank it seems he could pull through.

Again, it wasn't really the HEAT that killed the other two. It was the lack of OXYGEN caused by the heat. My other fish's were able to tolerate it but as said the TIG does require much more enriched OXYGEN. I believe this, specially in these HOT summer days.

So yes your tank Temp could be in the high 80's even 90's at times but with enough oxygen it will be fine. Something I underestimated in my tank :(
 
I am glad to hear he seems to be doing better. If you find spare pumps and powerheads around, do not hesitate to add them to your tank for a few days too. The more water movements and dissolved O2, the better.

this doesnt make sense though

how does lack of oxygen create a hump on there back?
 
what river are they from anyways?

I am not sure of the exact river but the collection points are in swift moving waters, sometimes near waterfalls. I have seen pictures of the collection points, very oxygenated water.


So you just give out advice without any knowledge on the subject?:WHOA:
