15 gallon aquariums A 24-inch tank holding 15 gallons or so is the first aquarium for countless hobbyists: enough water to stay stable, small enough to fit almost any home. Here is what to check in the kit and which stocking plans work. See comparison → 
Aquarium kits An aquarium kit is the easiest way to get started: tank, lid, light and filter designed to work together. But "complete" means different things to different brands, and something is almost always missing. If you want something small, under 8 gallons (30 L), see our nano aquariums: a different category with different limits. See comparison → 
Nano aquariums A nano tank fits on a desk and can look stunning, but it is not the easy option: with so little water, everything happens faster. Here is what to keep, what to skip and the gear it needs. If it is your first tank and you have the space, a 15-gallon (60 L) kit is more forgiving: see our aquarium kits. See comparison → 
29 gallon aquariums A tank of 25-30 gallons (about 100 L) with a 30-inch front is, for many hobbyists, the best first aquarium: nearly twice the water of a 15 gallon, more stability and room for a varied community without jumping to a big tank. See comparison → 
Betta fish tanks The betta is a tropical fish that lives for years when it has warm, filtered, stable water. The betta-in-a-cup or betta-in-a-vase picture is a myth that shortens its life: these are the kits that actually make sense. See comparison → 
Large aquariums (55 gallons and up) A big tank is more stable and lets you keep fish that don't fit in small ones, but filled, it weighs hundreds of pounds: think about the floor, the stand and the equipment before you pick a model. See comparison → 
Aquarium stands A stand holds hundreds of pounds for years, with water nearby and constant splashes. A good aquarium stand is not just any piece of furniture: here's what to check before you buy one. See comparison → Best sellers right now
