Ottos

[fishboy619]

not sure where this could go, catfish or not?
i know of the common ottos sold in shops, but i sometimes come across other species online. i know of the zebra ottos, but i wondered if anyone knows of other species of ottos. and if they have any pictures of them.
cheers

I found this article that says there are 20 different species. I don't know how accurate it is but you can have a read.
