Cleaned my Bettas home today

Peach and Nemo look happy now c:

They’re moving more and the tanks are like a million times cleaner than before.

Nemo = My little Brother (second)

Peach = Mines. (first)

Both Males, my female one jumped out of its bowl and died. ≡Δ≡

Apparently, Peach is turning white or loosing color. Along with Nemo, who is loosing his color. They're either suffering from stress since I haven't cleaned their tanks for about 2 weeks until now (because I thought I needed some Betta water. Tap water has chemicals in it in which I don't want my Betta to swim in. Since they are harmful.) Or because of Ich. 

Sigh. I need to go to Petco soon.
