I was confused as well since I still need to learn a lot, but check out this link to learn more about Tobi and his family:

Hi Marius

As far as my knowledge is a Tobi fish is a Fry that is much larger then its siblings and eats them. Tobi's are mostly plain coloured and are removed from the rest of fry.
Then the word Tobi Hi is scattered isolated red coloured scales.
If there is a variety called Tobi I do not know.

Regards

Roy
