A group of 12 or more is suggested for this species.
Another similar shoaling fish that holds its group quite well are the rasbora of the Trigonostigma genus. Harlequin Rasbora, Lambchop Rasbora, Hengels Rasbora. With any of these, at least 9 in the group.
I was thinking about harlequin,but I liked the look of the glowlights. They seem nice, I think I'll give them a try. Thanks for helping
