Mollie and Pineapple Swordtail sick. Help!

I have a 28-gallon tank that's about a month old. We have the pH and nitrate levels indicators and everything seems okay.

After about a week in the tank, our black mollie gave birth to ten babies which I put in a baby safe net and they have been doing well and getting really big.

I didn't change the bio-filter as quickly as I should and some algae had built up around the sides by yesterday morning. I changed the filter, took a scrubber to it and the Chinese algae eater went to work so that's been clearing up.

We've been reading up on the Chinese algae eaters getting hostile when they get older, so we got a Plecos yesterday afternoon in hopes to exchange the Chinese one eventually, but it was dead by nighttime. Our first fatality with really no explanation.

This morning, the black mollie mama looks like she's struggling. She just does not look good--hardly swimming. I did get her to eat a little. She also looks white on her gils and her belly--not spots, just white. Also the pineapple swordtail (female) is just sitting on the bottom breathing heavily. She has no white anywhere. The bully dalmation mollie is doing fine, the two guppies are fine, and the tetras are fine. The baby fish seem great, too. The only time the mama mollie will swim is when the bully charges at her.

Any guesses as to what is going on? I was hoping the Plecos' death was a fluke but maybe he was sick and got the others sick? I just don't know. I think the mama fish may be ready to have some more babies, so I'm really sad.

I just wanted to post a follow-up. My husband moved Mama Fish to a two-gallon by herself and she seems much better tonight. We also cranked the heater a bit on the 28-gallon and added some aquarium salt and the swordtail has perked up as well. :)

My mom says I'm too attached to these fish.

No such thing...

Can I ask, what did you have the temp set at before?

This is the song that never ends...

Get a liquid reagent test kit if you do not have one already. These are the best testing devices you can have.

We had the temp at 78 but now it's about 82.

Mama Fish was doing great in the two-gallon, then all of a sudden, she went a little wild and died. :( I'm so, so sad. I wish I knew what happened. I don't want this to happen again.

The swordtail is acting normal as are the others.

Now I have to tell her orphans that I've failed them...even if their mom would've eaten them. :(

I think a liquid reagent kit is a good idea. I am literally at the fish shop every day lately!
