My Hifin Platy's head is slightly down. His tail is higher than his head. He also seems to act weird; as he shakes a bit more when he swims. What could be the problem?
He could have a swim bladder problem. This can be caused by Goldfish Flakes and not Tropical Fish Flakes. That happened to me and since I have switched food it hasn't happened again. But I did read something the other day, it was called The Shakes. You can look it up and see if you fish has it. I haven't really had any experience with this before.
