Wall Mounted Fish Tanks I Need Help With My New Wall Mounted Fish Tank!!!?

I need help with my new wall mounted fish tank!!!? - wall mounted fish tanks

I have a new wall mounted aquarium, and I wondered if I could put a little salt water. Is it really important? It's like a reservoir of 9.15 liters, and yes, I think it would be nice with a clown fish, or something like that. So please let me know! Thank you! :-)
