,,,,,, 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.

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.
