Ok How about,
Does this have a good chance of working in the 90g planted tank? (all fish "full grown"):
1 large scalare(I will consider that this fish should be in another tank...I think so...?)
5 Neon Rainbows (1 or 2 male)
6 other full grown rainbows (4")
5" Friendly rainbow shark
5 Denisons Barb(Redline torpedo barb, indian flasher barb)
