I'm quite new to this, so need all the help I can get. One of my Platys can't seem to swim, and just keeps sinking to the bottom. What could it be, and what should I do? Thank you.
Swim bladder issue possibly caused by either constipation or an internal bacterial infection. You can relieve constipation by feeding thawed frozen peas, squeezed out of their skin, or daphnia. If that doesn't help treat with Esha 2000.
