5 boesemani rainbows. 8 guppies. 2 dwarf puffers. 3 Siamese algae eaters. 1 red rAinbow.
I feed my fish some black worms yesterday evening and a few hours later the fish were swimming at the surface of the water. I did a 30% water change. Didn't help, I have an air stone and two filters that fall onto the surface of the water. So I know lack of oxygen isn't it. I also have live plants.
I feel it has to be the black worms. Does anyone have an idea what it could be?
Here is my tank
