You should have seen it at fisrt when it happened, poor guys was belly up, im thinking it was dead, when he swims up and down in circles then smash its head either the glass or gravel. Sometimes when it eats, he eats while its belly is up, and poor thing cant even go backwards, i didnt post it before, i only showed it to few people cause i was just waiting for it to die. But i just did my normal routine on WC, add some aquarium salt, next thing i know it got better.
Its a great feeling when you can bring one back from the brink. I feel the same about my heterospilus...little girl was knocking on heavens door lol i could never sell her
