I have 3 rbp and the stress out when i put a bubble stone in the tank and they don't eat so i took it out. THe other day i was watching them they were breathing pretty hard so i had to put it back in for the day is there anyway to get oxygen in the water other then a bubble stone that won't stress them out??
 
didnt you already ask this question, oh well, doesnt matter

Did you try hiding it, or burying it under some gravel, its weird that they would freak out about that :confused:
 
One of my filters has a venturi airation. I have the impression that it oxyginates water a lot better than the airpump. When it is on you can see tiny air bubles ascending to surface all over the 130g. The airstones produce relatively big bubbles that do not dissolve and the air appears to be mainly wasted.
 
Try putting the stone closer to the surface of the water.
It won't be so close to their swimming area and it will still still disturb the surface.

You get almost no oxygenation from the bubbles in the water .... the bubbles only help because they bring water to the surface.
 
you can try lowering the water level in your tank . if your using HOBs the waterfall effect will greatly increase the gas exchange plus there will be more area btw the water level and your tank lid. also check your temps, as the higher the temp, the less dissolved oxygen the water can hold.

you don't give any information about your aquarium (filtration, etc..) Not knowing what equiment you have, it's hard to offer advise that directly applies to your set up. Simply put, The surface of your water needs to be disturbed one way or another to de gass (oxygenate) your water. Several good options were offered by other peoples post here. Bubbles in your water do very little to oxygenate your water, it's when the bubbles hit the surface and disturb the surface of your water that de gassing occours. Power heads (as some one else mentioned) aimed at the surface will agitate the surface of the water and cause de gassing. Basically do something with your equipment to agitate the surface or your water. Also, if you have not all ready, make sure your water quality is good. By this I mean test it, not look at it and dertermine it's ok because it's clear. If you have ammonia or nitrites (espcially nitrites) this often will cause fish to have labored breathing.
