I had never thought of this possibility before Bob Steenfott mentioned it in his Monday livestream...mostly because these halfbeak species are pretty small (1-2 inches). I wanted to put 6 of them in my 17 gallon heavily planted tank with my 6 licorice gourami and 12 chili rasboras. Will this be a problem? I pictured the halfbeaks staying near the surface under my red root floaters and Brazilian pennywort...but if they'll eat my chilis or make them too nervous, this is a no-go (and I'll be super sad...I really wanted to get halfbeaks! Fish health and safety comes first though).
This is the tank they'd be going in. Sorry it's upside-down...there doesn't seem to be a way to rotate it in the forum (and rotating it before uploading doesn't work either).
