Cleaning bother's tank

TANK UPDATE:

Been taking care of tank for 22 days now, and the nitrates are significantly lower, as well as dirt in the gravel.

Fish are fine, and now they are living in a planted tank. About 8 twisted valisnerias to begin with.

I'm gettin a couple of cories to fill the bottom part.
