That FH above was for 200$(USA dollars)
Though I would be buying a juvenile. They sell them for about 10$.
I find oscars and FHs are both cool looking fish. Just can't choose .
Will be sure to post it on Fl which one I choose
Oto's like to be in shoals of 6 minimum like said by jkelly.
As for Cherry Barbs they should be in 2 females : 1 male(just reminding).
And no i dont think your crazy( i was like that when i started my tank too)
