Fish hanging out with the bubbles
Please help. I have a small 50 litre tank with 14 guppies, male and females. They all seem to be hanging out at the filter all pointing their mouth to the bubbles almost like they need oxygen, so i've added oxygen by placing a airstone in the water under the small stones but then they hang around those bubbles. i am loosing about 1 fish every two days and just don't know what it is. I have a small plant but it's too small to produce too much CO2, the water doesn't smell. i just don't know anymore?
