i have a platy fish she's a female and she hasn't eaten anything all day (i gave her food but she didn't care) she keeps pooping long redish things and she hides behind decorations or stays in a corner. When i put my finger close to the aquarium to check if she wasn't dead she freaked out and started bumping into the glass (she usually doesn't do that when she's scared) I've had her for 3 days and she's my only fish. Im thinking she might have gotten pregnant at the pet shop i dont know tho :(
If the tank was not properly cycled before she went in, the water qualityu may be affecting her. Check the water parameters first. Temperature should range bewteen 68 F and 78.8 F (20C to 26C). Using a home test kit, ammonia and nitrites should read 0 ppm. Nitrates should be 40 ppm or less. Platys do best in a pH of 7 to 8.3. Adjust parameters as needed and see if it makes a difference in her behavior. Offer a variety of appropriate pelleted and flaked food as well as freeze dried to see if she has a preference. Platys are livebearers with a gestation of around 28 days. She will become noticeably bigger as her date approaches. If she is pregenant and has fry, you will need to separate her or give the fry plenty of cover in the tank. If not, she will eat them. The stress of a new tank and water may also be a factor. Hopefully, with some adjustments and different foods, she will perk up.
