Are there more than one species of tinfoil barb?

Regular tinfoil barbs have black in their tail and can reach 14". I have seen some truly goliath ones my uncle used to have, like oscars that moved like torpedos.

Red tail tinfoils grow to around 8"-9" I used to have 12 of them in my 225 and they were all fully grown and used every single inch of that aquarium. It was 3 feet wide. So I recommend they have a lot of room

I had 'albino' ones that were pretty much pale orange with orange eyes.

barbonymus schwanenfeldii and barbonymus altus.
