LED Lighting and the unique Half Moon shape of these aquariums make a stunning combination! The LED Light provides a natural shimmering effect in the water, is energy efficient and is powered by a low voltage adapter.

Each aquarium has a clear plastic canopy with a feeding hole, and cut outs for the filter. The canopies also help to reduce water evaporation and keep fish inside the aquarium.

Rated 5 out of 5 by from Great aquarium I purchased this Half Moon 10 gallon tank at a pet store along with a fish and got home only to find the light bar and power supply had been removed from the box. Being the store was 45 minutes away and was now closed, I went ahead and set up the tank. The next morning I called the Care Team (1-800-322-1266) and spoke with Tammy about the missing light and power supply. She was extremely nice and helpful and I am being sent a light/plug. It is refreshing to get great customer service from a company. The tank is beautiful, the internal filter is silent and the flow does not bother my Betta Fish at all. Great product, great company experience and I will definitely buy more Marineland products in the future.

What is a table size for the 20 gallon half moon aquarium. Measurements.

Asked by: Fishpee
We do not recommend using tables. They may not support so much weight. The dimensions of the tank are 24 x 12. We manufacture a stand for this tank, which is what we recommend using. BREX

Do u ship your bigger half moon aquariums to Edmonton AB? I saw the 10 gall at PetSmart, but would love to know cost ($CAD) and dimensions of 20 gall also 30 gall.

Asked by: Neala
We do not sell direct, but we do sell these tanks in independent stores too. You may have to pick it up over the border at a store in the U.S. if there aren't any in Canada, but visit our dealer locator by clicking on the Buying Options link and entering your postal code. BREX
