Have you tried doing a 3D DIY background? Those can come out amazing and they are fairly simple to do although it does take time and a bit of sculpting skill but it's certainly different! You can construct anything out of the styrofoam including rocks and logs and then just paint it with drylok of different colors using cement tint! You can hide your equipment that way too ^_^
And a note, white clouds are colder water fish so they like the 60-70 range.
