Hello and welcome to Petco Pet Education Center, formerly Petcoach. You can try a few different routes to see if anyone would like some of your fish. You can post on Kijiji, or you can go around to your local pet stores and vet clinics and let them know you have free fish for good homes. Pet stores might be able to help you out if they have a bigger tank. You could also put up flyers. Best of luck finding good homes for your fish.

Platys, Mollies, Neons, Dwarf Gouramis and Cory Cats are all excellent choices. Be sure to not overstock the tank and allow it to properly cycle before adding fish. You would need to contact the Petco in question and ask them directly. Some locations will accept fish to rehome if they have the tank space. Most local fish stores will not, due to risk of disease or parasite transmission.

There are several causes that can provoke these signs fro water imbalances to specific diseases like swim bladder ones. This problem requires a quite radical but logic approach. Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. High ammonia levels, PH imbalances may be responsible for that. Oxygen concentration and quality of the filters should be determined as well. If water quality is good and there are no major imbalances, your fish should get examined to look for any sign of bacterial/fungal infection and eventually water should be treated. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Check water chemistry using a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20 ppm or less. Perform partial water changes, if necessary, to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Check the temperature as well. Low temps can affect appetite and activity in fish. Once water parameters are stable, she may begin to eat again. If not, you can soak food in a bit of garlic juice to stimulate the appetite and provide a boost to the immune system.

Mollies do come in gold or orange colorations, but it is difficult to determine from that angle. If you can repost a broadside picture in a new question, that may make identification easier. If it is an egg laying species of fish, the third image could be an egg but I have reservations saying definitively without something for scale. It looks too large to be an egg. As an aside, if you leave the Molly fry in with adults, they will likely be eaten. You can separate the out, remove the adults, use a breeder screen or provide plenty of cover for them.
