How many tinfoil barbs should I keep?

[swervo513]

I recently bought three tinfoil barbs and they seem happy. However I was wondering what number of tinfoil barbs is ideal for them to be truely happy and schooling. Should I add more or is 3 ok?

Thanks

Hi Larry. They'll probably be ok in a group of 3, but adding a few more wouldn't hurt. I assume they're in the 180gal?

yes sir... 180 gal.. I gotta think about how that would effect my bioload since I have some fish that get large
