all of my cichlids are on the surface of the tank sucking the top of the water. the feeder fish i put in there that would normally be devoured in minutes are also all on the surface doing the same thing and none have been eaten. my catfish, in the same tank, hasn't eaten either. the only one acting normally is my loach. what's going on and how can i fix it?

I dont remember all the things it could be but one is not enough oxygen in the water. Are your filters working? Maybe try doing a big water change and see if that helps.

Yep, water change! The top of the water has the most oxygen so if the tank needs a water change or for some reason is not getting enough oxygen, the fish tend to go up to the top of the water.

I agree with the water change... also... is your air pump specified for the size tank you have?... maybe its just not powerful enough to supply enough oxygen for the amount of water you have

i did a big water change, vacuumed out the rocks on the bottom, added water conditioner and no change. so, i did a water test and my nitrates are high. the water conditioner doesn't seem to change this. any suggestions?

nitrates are the result of the ammonia breakdown process. If you havent been keeping up with the aquariums maintenance, this can rapidly get out of control, in addition to many other issues that happen simultaneously (not trying to be snarky). This site goes into more detail: <a href="http://www.bestfish.com/oldtank.html" target="_blank">http://www.bestfish.com/oldtank.html</a><br>
A dramatic water change could be a bad thing, if the tank has been let go for too long. It can shock already weakened fish. Do small, regular changes for several days, check your water parameters regularly.<br>

Edited to say: Im glad you did a gravel vac! It helps immensly!
