My favorite schooling fish.

1) Harlequin Rasboras. These guys are EXCELLENT schooling fish.
2)Tinfoil barbs. Awesome to watch them swim in groups and do some weird stuff against the glass. Good fast fish to put in cichlid tank, because nothing can catch it.
3)Silver dollars. I like these, because they are sort of like tinfoil barbs, except they are pancake style! They are also more expensive =(

Danger Will Robinson! Those Tinfoil Barbs will grow huge. Easily 6-8 inches.

I have Rasbora hengeli. They are slightly smaller and slimmer than Harlequins, and their colouring is more of an irridescent orange.

Yuppers! I know those tinfoils will grow big, but i have the space for them. I've never seen those rasboras before... i'll look out for them. Irridescent orange is nice...

To this day, my fave was a 500 gallon aquarium...black gravel, black painted back....with a school of 750 neon tetras and a school of 60 albino Cory cats...it looked stunning.
