A site is selling these "doctorfish". After some research, these fish look very different from the "original" doctorfish. The site says these live in hot spring waters and close springs, and help you get healthy by eating dead skin and parasites.
Has anyone seen or kept this fish before? I think it's cute!
I used to work in an LFS and sometimes we could order what was called "doctorfish" from the list, they were always Garra.sp . The fish on that picture is no Garra.
I didn't say that two different species (or more) can share the same popular name though.
In the sea in spain, the local marine fish will nibble your legs & pull at the hairs (this applies to us gents only). It is a crude take on the well known cleaner wrasse kept by marine keepers - some other fish - like the Garra sp. do similar things sometimes but i doubt if that was the pictured fishes sole source of nutrients....
