Algae, Random Death, Ammonia Poisoning (When Bought), Ich,

[TotallyTropical]

I JUST finished treatment for Ich, and it killed only killed my male Swordtail, then the day after I successfully finished treatment, my female Swordtail died with a weird brown blotch on the side of her, and now my Platies have what looks to be Tail Rot and Fungus! I'm treating it now with API Pimafix (which has worked for me before), which only one of my Kuhli Loaches absolutely HATES! (Though it says nothing about hurting scaleless fish....) Am I doing something wrong? The Platies look horrible, with their fins clamped to their side 24/7, and they will barely eat a thing! I would just like to know if there is a cause for all of this. I am not over feeding, before I did a water change a few days ago, my PH was at 7.8+, my Ammonia, Nitrite, and Nitrate were at .25 (API Ammonia, Nitrite, and Nitrate testing kit is all in one, so I don't know).
Edit: It's a 10gal. tank.

im no expert but a few questions for you......how big a water change did you do? you say, my Ammonia, Nitrite, and Nitrate were at .25 (API Ammonia, Nitrite, and Nitrate testing kit is all in one, so I don't know). is your tank cycled? ammonia and nitrite should be zero, bad water quality often causes health problems with fish, however, it sounds like your not using a liquid based test kit, so your readings could be higher than this, are you using strips?

No, I'm using the liquid test kit, and that was before the water change. The tank has been cycled for about 7 months, and I did a 25% water change.

Well, one of the Platies died, and the other one looks like it might have Dropsy.
