my oscars are acting funny, wondering if anyone else has seen this problem.
for the past week or so they are hanging out on the bottom of my tank, sometimes kind of sideways, not really eating much or moving around like they normally do. i feed them feeder fish every now and then from the petshop and they normally eat all 20 that i buy within the day, but i still have about 7 left from almost 2 weeks ago, dont know if they might have gotten sick from them or what. i do weekly water changes and test regularly and everything is perfect.
any ideas?

Can you give us the numbers of those readings, like ammonia, nitrite and nitrate? Also what size of tank they are in and how big are the oscars? How long has the tank been set up and how long the oscars been in the tank?

If you are buying feeders from lfs could be the feeders were sick.

tank is a 75g oscars are about 7inches long each there are 2 along with a pelco that is about the same size and a blood parrot that is not that big. 0 ammonia o nitrites and 20ppm nitrate i think it was, had the tank and been cycled for about a year, oscars swim around for a little bit then rest at the bottom just started about 1.5 weeks ago

Sounds like they caught something from the feeders. Also can be stressed as oscars need a much bigger tank when there is 2 of them plus other fish. They are very messy fish and needs lots of room and lots of water changes. How often do you do a water change on that tank. Hopefully every couple of days with the waste producers you have.
