You could potentially mimic that tank using low-light plants if you're willing to forego the grass.
If you're set on the grass and carpet-type plants, you'll need high light, fertilizers, and CO2
. I'm hesitant to give a specific wattage because the wpg
rule doesn't work perfectly with smaller tanks. A 2-bulb 24" T5HO fixture with 6500K bulbs would probably be adequate. DIY fixtures using compact fluorescent bulbs are also an option.
