Hello, I've only had my tank for about 3 weeks now. One of my Mollies had a pretty bad case of Ich for about a week before I was able to recognize what it was. Before treatment he had begun to have trouble swimming (almost like he was swimming in a comma shape) and was resting at the bottom of the tank quite a bit. I removed the filter cartridge and used meds in the tank for 3 1/2 days and then did a 25% water change last night. The Ich appears to be gone, and he definitely has some strength back BUT his swimming is still irregular and he seems to have a hard time swimming straight, as in he keeps turning vertical with his tail pointed towards the surface. His breathing seems okay, he's not gasping and he is eating well. Any suggestions or help? It makes me feel so sad to look at him when he is swimming this way, is there anything I can try that may help him get back to normal? Could this be a side effect from the Ich?
