Hi everyone my first post and a sad one. My Pulchra seems of colour she seemstobe bendingher head back all the time, hangingaround the top of the tank and struggling with her balance a bit. S he is eating fine and her mate seems in perfect health. The water parameters are good and tank mates seem to be ok. My thoughts were that it may be soom sort of swimbladder problem, any help much apreciated.
