Sick Pregnant Swordtail and Sick Male Swordtail!!!!

Hey guys, earlier today ~2pm (currently 5pm), I saw a red patch behind my swordtail's fin and right in front of it her fin looked to be chopped in half (hard to see in pictures). I immediately transfered her to a 2.5g fish tank that I had, it's not the best for her, but it's all I have and I was afraid to keep her in the community tank with the other 30 fish...

The male swordtail's tail fin the bottom portion also looks to be missing exact same as the females, and they both have white fuz on the end. I thought it was tail rot but was wondering where the red welt comes from... it looks like a red patch with small white dot.

Also, the male's poop has been long and string (I think just once)

I have been wondering what what medications I need to get, what the diagnosis is.

Lastly, I am wondering if I should transfer the mail to my makeshift 'hospital tank' but am afraid to because the male doesn't have the red welt yet.

And the female is pregnant if that makes a difference.

Thanks for your time.

These pictures are only of the female fish:

 

sounds like it could be a case of ammonia and nipping? Do you have your tank readings?

 

Sure. Ammonia: somewhere between 0-0.25ppm, I did a 30% water change
Nitrite: 0ppm
Nitrate: 0ppm

Tank is around 2 weeks old, but to get it started I poured in tetra safe start.

Pictures have now been added guys! They are hard to see so you may need to tilt right and enlarge. The red welp on the female is evident but the torn fin is hard to notice.

 

That looks like an exposure to ammonia issue to me. Although it looks quite large. At this point id keep her water prestine, maybe add some java moss or some type of plant for her to feel safe in. See if you can get her to eat some fresh garlic or add some garlic juice to her food. Stress coat will help heal the fins, with prestine water. But it takes a few weeks. Good Luck

 

Ok I'll test her hospital water daily and change in case of ammonia. I moved male to 1 gallon temp. tank in case he had the disease, do would it be safe to move him back? Also found one dead catfish so that may of lead to ammonia though I don't know what caused
me to lose the catfish... Thanks for help

 

What water conditioner did you use with TSS?
After weeks your cycle should be further along than that.

 

I used tetra aqua safe regular conditioner.

 

Ok cool. There goes my therory.
TSS isn't 100% fool proof. Even tetra admits you may have to dose again.

Ok thanks... I'll look into it.
