Stocking??

[BIGMONSTER]

Ive got an empty 150 72"x 18" with an AC 110 and a 30 gallon sump.
Im looking for something kinda colrful and not too aggresive or something rare and smart.
WHAT should i do

I'd keep loaches and severums in it. Either that or a Grrr tank with loaches of Syncrossus genus along with Yasuhikotakia modesta, Yasuhikotakia morleti and Y. eos. Dither fish will mostly be arulius barbs, filament barbs, Apollo sharks and/or tiger barbs.

You have a lot of possibilities. A school of clown loaches would be cool, with a bgk. And maybe some discus? Sevs? Dunno. What do you like?
