I think they should be bog standard, out of the box.
You can add a heater only.
If you happen to have a tank that has two lamps, then so be it.
It is more of a challenge to see what can be achieved with an off the shelf tank as inspiration to others with limited space or budget.
You should be able to aquascape it with whatever you like in regards to rocks, driftwood, substrate, tacky ornaments and the like. My only no-no would be fake plants.
Another consideration is with the likes of the Aquastart that has UGF, which are not conducive to putting any growing medium in a tank, should you be allowed to not install this and just use a sponge filter instead?
