Difference between heavy breathing and holding eggs

Here is a photo of her. I will try to snap a better shot asap.

It does look like she is chewing gum. She is staying hidden behind a cave in the upper part of the tank. She does come out and swims around a bit, then the male chases her back in the cave. She is showing vertical barring which makes me think she is stressed. Over all, she does'nt look terrible, but the younger females I have look great in comparison.

Here are two more photos.

Well she did not make it...I'm really not sure what it was that did her in.

For the rest of the fish, I performed a water change with vacuum and fed the fish antiparisitic food. They all fed and I will keep up this rountine for three days.

The long story here is that I got two of these fish via the mail about 10 days ago. The problem is they spent four days in the mail and most likely were very stressed. One of them died a few days later and this one was hanging in and I thought she might make it. I'm not sure if was bloat? I do not have much experience with this disease. The first one that died did have a bloated look to her. This one did not look bloated. ???????

Regarding "white stringy poop". Is this always a sign of bloat? It seems I've seen this every once in awhile with my fish and nothing comes of it. I'm kind of nervous treating with clout. Twice that I've used it, it seems to be the nail in the coffin. How hard is stuff on healthy fish?

The lesson here is that I'm going to quarantine my new arrivals from now on!

Thanks,
