This plant looks like a Haworthia, perhaps the one below, and not a Gonialoe.

Zebra Haworthia (Haworthiopsis attenuata)

I will be moving it to that entry unless you or anyone else has some specific information pointing in the direction of a different ID.

Oh ok thank you! I always thought it was a tiger aloe. Very much appreciated.

Take a look at the photos on that page and see if your plant seems to belong in that group... otherwise we can move it elsewhere, if there's an entry that fits them better.

Thank you Baja, and it seems that the plant belongs in that category you sent me, because a lot of other pictures look like the one I posted.
