elephant nose kinfefish

Sadly due to the lack of time, I could not get the 200x60x65cm tank, however i do have a 33 gallon (80x35x45cm) tank, would it be okay, for a sternarchorhynchus mendesi? (usually 17-19cm). I heared they are quite adaptable and friendly. Tipps are appreciated. Here is a photo of the tank, in case...

It was sold to me under the wrong name, and unfortunately can not find anything but the more black colored Elephant nose Kinifefish. This guy has more brown mottling. I will try to get a better pic. They are going for about $35 at a local shop in Southern California. Thanks, Shane.
