You should get 2 more Corys for the school, the white clouds are cold water fish. The rasboars like larger tanks.
Think you've two different species (C.habrosus and C.pygmaeus).
The rasboras are two different species as well think.
I'm going to be moving the Rasboras over to my 20 high gallon in the next month, when I move my albinos, pandas and honey gourami over to my 30 gallon, definitely plan on getting some more pygmies just like to get 3 fish at a time for my tanks.
