Oscars laying on the bottom of the tank

[ttownsend1]

I have two oscars. They started laying in one spot on the other side of the bubble strip.
They lay right next to each other. They are not eating. No spots or film on them. All the rest of my fish
there is no change. I bough two peacock eels last week. I came home one of the oscars had it in it's mouth.
The other eel stoped eating after that and died. What could be wrong with my oscars?

what size of tank are they in ?
what tank mates do they have ?
whats your water readings ie ammonia , nitrite , nitrate and ph ?
what water changes do you do % and how often ?
what kind of filtration do you have on tank ?
sorry for all questions but the answers help us to help you

My Oscar was doing a similar thing when I was having my crazy water quality issues. I think it was stress-related, he was leaning to the left on the bottom of the tank and the Jack D. was guarding him (strange sight to see, lemme tell ya). Now that I have the water quality under control the O is swimming around like a champ! I've never seen a happier lil fish. Are your water parameters ok? And did it happen after you added the two eels?

If you can provide us with the info Alan requested we may be able to help.

They are in a 55 gal tank, Aqua-Tech 30-60 filter. I just changed 25% of the water.
The PH I'm not sure. So I changed the water. I have not changed the water in awhile.
There is 2 large Plecostomus and 4 Tiger Barbs in the tank with them. I 'll cross my finger
and see tomorrow.

Changed the water they are swimming around.

It's like 1 in the morning here in Scotland, so I'll make this quick..

You are really over crowded in that tank, and you will start having even worse problems as time goes on.

Unfortunately you are going to have to get rid of some fish.

Agree with Jack. You will need to thin out most of the fish. Or get a 100-125 gal.

Just how often do you do W\C`s and how much ?

,,,,,, So I changed the water. I have not changed the water in awhile.

Here is the problem, you are under filtered and not doing proper tank maintenance as shown here http://www.theoscarspot.com/viewtopic.php?f=26&t=13651

You are as the other have said over stocked and this too will be causing you problems.

The PH I'm not sure

Do you know any of your other water readings

Changed the water they are swimming around.

That's because you freshened things up for them, I would do another larger change of around 75% as I will guess your nitrates will be very high.
