What comes in the box?

The glass tank with its black rim and silicone seals. No lid, light, filter, heater or stand is included, so plan those separately.

Is 20 gallons enough for a betta?

Yes, and it is more room than a betta needs. One betta with a few shrimp or snails leaves plenty of space, and the 24 in length suits a small community instead.

Can I use it for saltwater?

Yes. The glass and silicone are fine for saltwater, and the footprint suits a small reef or fish-only setup. You will need a filter, heater, light and, for corals, a powerhead.

Does a standard 20-gallon long lid fit?

The tank is 24 x 12.5 in, close to the common 20-gallon long footprint. Check the lid's listed dimensions against those before buying, since the rim adds a little width.

How much does it weigh when filled?

Water alone is roughly 170 lb at 20 gallons, plus the glass and any substrate or rock. Set it on a stand rated for well over that, not a shelf or desk.

Is it good for a planted tank?

Yes. Clear glass and the open rectangular interior suit plants and hardscape. You supply the light and substrate, and a tank this shallow takes most mid-power lights.

Our take on the SubstrateSource 20 Gallon Glass Aquarium

This is a 24 x 12.5 x 17.25 in rectangular glass tank holding 20 gallons, sealed with aquarium-grade silicone and topped by a black rim that takes standard lids, lights and filters. The open rectangular footprint gives long viewing angles and room for plants, hardscape or a small reef setup, so it works as a starter community tank or a compact aquascape. Against plastic and acrylic 20-gallon tanks it wins on scratch resistance and clarity but weighs more and chips if knocked. It is a bare tank: no lid, light, filter or heater, so budget for those on top.

Pros

Clear glass shows fish and plants without the haze of acrylic
24 in length gives a wide viewing window for its volume
Black rim accepts common lids, lights and hang-on filters
Aquarium-grade silicone seals suit long-term water contact
Rectangular shape leaves the full interior open for scaping

Cons

Sold as the tank alone, with no lid, light, filter or heater
Glass is heavier than acrylic and chips on hard knocks
Rim and silicone need a careful check for leaks before filling
20 gallons limits larger goldfish and big community fish
