I would not go with a keyhole, because you want something colorful, and a keyhole is not that colorful.
Keyholes are interesting fish.it needs to grow to a maximum of 4-5inches and be quite colorfull/interesting and be relativly peaceful.
or you could get a pair of blue rams providing you keep a clean tank
He already has bolivian rams.Right i have a 108l tank, with a small shoal of False Harlequin Rasboras and 2 bolivian rams,
He's already said that he's considering opaline as his choice of gourami.dwarfs are weak fish that like gettin stuck in rocks and other decoration
Dont go for Dwarf Gouramis, see my earlier posts on them, try the Pearl Gourami instead.
