This is the Top Fin Enchant 3.5 gal fish tank kit, so it comes complete with lights and filter. It also includes an Aqueon 50 watt heater, which was purchased separately. You can't keep tropical fish without a heater, so this makes the kit complete for any tropical fish.
It is a nice size tank for a small space. It was used for about 1 month, so is in like new condition. No damage.
