+1 with bruinsbro
but maybe larger schools of each fish so make it kind of a rainbowfish takn..............they look amazing when you have separate schools of each
so maybe.................
8X praecox(dwarf neon) rainbowfish
6X boesemani rainbowfish
8X threadfin rainbowfish
8X red irian rainbowfish
6X orange laser cories
8X forktail rainbowfish
OR
maybe traditional like takn?
4-6 Angelfish
16X Schoolers(harlequin rasboras, rummynose tetras, etc.)
2

Tiny Schoolers(green neon tetras, micro fish 1/2" size, etc.)
6-8 Corys
1 Pleco(ABN/BN/Starlight/etc.)
4-6 Loaches
gourami maybe?
good luck!
