how the hell do you guys come up with overfeeding as the issue??

disease is the suspect

a) Oscars feeding behaviour
b) The timescale was so short / acute

What conclusions have you reached?...

disease is the suspect

This is exactly what i am concerned about...Disease....but in my tank, the fish show no sign of disease, but as i said earlier, i do not feel like they are breeding as rapidly as they should. As far as my cleaning habits:

I do a 30% water change 2x a week, which is a must or my nitrates go thru the roof and i will lose a fish per day or so...although i rarely EVER lose a platy, which is the supposed "killer fish" to the oscar, but the guppies i think are more sensitive. I use stress coat for water conditioner....i dont use "hot water" but i try to mix or whatever to get as close to the 76-78 degrees i keep in the tank when im putting it back. I have an Eheim 2028 filter (rated for 192 gallons i believe?) and i change the white fine filter on a regular basis, probably monthly if i had to be accurate.

My brothers habits are similar, but he keeps his tank colder than i do, and yes he does the same 30% twice a week, uses normal tap water with a conditioner...but i really dont think this is anything he did...i am really believeing this was my fish...

He did tell me that this happened to another oscar he had a long time ago, and he purchased some feeders from Petco, and almost the same thing happened (his feeders at that time were just regular gold fish)

If it is disease that you guys suspect, how do you test for such a thing???
 
No one has any advice on this problem?





:yuck:

you dont

you just try to prevent it from happening again, alway quarintine your feeders.
 
The only true thing that could affect them THAT QUICKLY would be a chemical issue. Even if by chance you tranferred a disease its gonna take a lil while to truely affect them. Does the water smell of bleach or soap?
Have children? I bet someone either:
A. Threw something in the tank...chemical or whatever. It could have simply been on hands and was transferred when they were put in the tank.
B. The container you used to transfer the fish was contaminated with a chemical (still can be transferred very easily.)
C. the net or hands used to remove from the transportation container was contaminated.

If either of these are the case, with chemicals, not true cure but clean water and time. I hope its not a chemical issue. But it very well sounds like it to me.

he just messaged me and said that his eyes and scales are turning white....and this is an albino oscar, so he is an orangish color normally.....

He also mentioned that the firemouth acts dead, then goes spastic, then acts dead, goes spastic.....etc

Furthermore to my above post something is impeding the ability of the gills to provide proper transfer of O2 to the bloodstream. The listlessness of the firemouth and the discoloration of the Oscar proves that. I think it is NOT a disease issue but a chemical abnormality.

This could also be a valid point. Acute poisoning. Or it could be the accumulative stress due to such gross overeating and metabolic disorder via poisoning, the synergictic effect of the two. Disease? No! Far too sudden. What also concerns me is the apparent hypoxia, evidenced by the respiration rate you witnessed, AND, you state if you don't do two 30% water changes per week your nitrate levels go through the roof, you lose a fish per day etc. Whilst it is great that you are doing two water changes per week, these should be seen ideally as a prophylactic measure, not a reactionary one.Your tank is far from overstocked, you are running an excellent canister filter yet your nitrates go through the roof. If these two water changes from the tap keep your nitrates under control then your water supply must be nitrate free. However, if you are not grossly overfeeding, are not overstocked and have a bio-muture filter thsi simply should not happen. Also most species have a high the toxicity threshold for nitrate, it is VERY, VERY unlikely nitrate could kill your fish short term. Ammonia and nitrite most definately, they would impair haemoglobin function within red blood cells. How often are you testing ammonia and nitrite? Have you cleaned your canister filter lately? If so how? Are you overfeeding? Has thee been any opportunity as tankyou suggested where your tank could have been tampered with? Filter turned off, something added to the water etc? Anwer all these questions and you may get to the root cause of your problem and be able to take corrective measures.
 
He probably won't be able to diagnose what hapened. 15 platies are not an overfeeding issue, no two ways around that (exxecpt if we're talking baby oscar ). The meeki barely et any.

Disease is absurd at such a speed.

I agree with the possible poisoning. The bucket you guys use, was it only used for fish? Small children?
As already said. Don't fret. Your tank is not doomed. To a good cleaning and water change and start again.

Good luck
