Honestly, with that bio-load you should be doing 50-75% water changes 2-3 times a week.

your gonna need a bigger tank than a 125, pacus get over 2'.....

On the 125 be prepared to upgrade again if you want to keep all those big fish. Also, I recommend a water change/gravel vac of 50 percent every two weeks minimum.

Check your Nitrates

It sounds to me that your Nitrates could be off the chart (this happens to overstocked tanks)Most of the time odd behavior is related to water issues.

Just for the record ,my tap water readings are as follows:ammonia 0; nitrate 0;ph 8.0.I tested my tank water nitrate and found that to be high 6.0. I think the r/o water was dropping my ph down for a while as I hadnt tested it in a couple of weeks and it took me a while to get back to 7.0 When I said my tank ammonia was .15 Iwas referring to the reading that is so slight that its hard to tell if it is yellow or really yellow. Ive since donated a couple of my fish and have done several extra water changes to reduce the nitrate level. Oscar looks much perkier although hes still spitting his food out. Hopefully he'll make a complete recovery.Thanks for the advice from the members and the all knowing all seeing moderators
