I had a dalmation molly, male and fancy guppy, male... I also have other fish... but bought them yesterday at petsmart... so today I bought a pleco and a tetra from walmart to go in the tank, then I went to check on them about a 2 or 3 hours after buying the 2 fish, and me two fish were dead, and I have no idea, did they fight? Did they get a disease, also my tank temp. was about 85 degrees , when my mom heard, she said it may be because the temp. so i turned off the heater and poured some cold water in there to cool it down to about 78, what was wrong, btw the tank is brand new.
