Bloating and wasting (two opposite sides of the spectrum) are both symptoms of Camallanus worms. I'm not saying that's what is going on, but you can't really rule it out just because they don't look skinny. Bloating is also a sign.
Are there plants in the tank? If not, I would leave the light off all the time. That's what I do with my hospital/quarantine tanks, to keep the stress level down for the fish. Also, you can add some fake plants you buy at walmart (craft section) or Michael's craft store to help them feel more secure. I wouldn't use freeze dried foods, but instead frozen bloodworms.
Next time you go to Petsmart for your water test, make them tell you the numbers, and write them down. I bet it's something as simple as water quality
