That's pretty much what I have in my 30g next to the pothos, but I used a dremel to make a slit and put a hook to hang it on the tank because I was worried the sunction cups wouldn't hold once I added the gravel and realized how heavy it was. I got mine at walmart, and I think they have them pretty much anywhere with shower supplies if you're looking for one . If you're gonna end up adding a hook though (I used the clear plastic ones in the bath section of walmart, the over door hangers), you can use pretty much any square basket you choose. There's also a ton of other baskets at walmart with hangers and suction cups that seemed like they'd work for various aquarium plant applications.
