CichlidFish.com - Fish That Think.

My Red tiger Oscar is about 2 inches big and it hasn't been eating and has been pooping alot the last three days and it seems to be breathing heavily and opening its mouth all the way when it breaths. My other tiger oscar is doing fine though I was just wondering if if this is normal and if hes going to be ok?

Can you give us a little more info?  How long have you had your Oscars?   Do they have any tankmates?  What sort of filtration are you using, and how much and often do you change water?

It would also help to know a little bit about their water conditions.  I'm assuming you have a water test kit.  If not, your lfs will likely be glad to test it for you.  Essential info includes readings of:

ammonia (should read 0)
nitrite (should also read 0)
nitrate (20ppm is good, 40 or over is a concern)
pH reading would also be of interest.

Let us know.  Good luck!

Well he seems to be doing better now I dont know what happened to him but hes swimming around the tank with the other oscar now and eating.

Ah man it died it just wouldnt eat and died. The other oscar is thriving though. Thats the second fish from petsmart that has died so I am going to take it back and get my money back and go get another black tiger from THE AQUIARIUM.

That's too bad.  Did you check out those water measurements?

Ya they were all within normal limits. I found out from my friends mom when i was waiting in line at the high school to get our books I was talking about to her because they have oscars that my oscar had ICK. So I returned the dead oscar and got some stuff to treat the water so the other fish dont get it.
