Aquariums come in all shapes and sizes so it may be difficult navigating the murky waters of the aquarium market to find a suitable tank for your next setup. 40 gallon aquariums offer a medium tank which is versatile and able to fit in quite confined areas.
Common uses of 40 gallon tanks include breeding and small reef setups with plenty of kits available on the market for beginners which include many of the essential accessories an aquarist may need or even stands and custom hoods. With so many choices available for when you’re looking to purchase a new aquarium, below is a brief overview and review for nine popular, common 40 gallon aquariums listed on MyAquarium so that you can make an informed, knowledgeable decision on your next tank.
The SeaClear 40 gallon aquarium is a great new offering by SeaClear that is reasonable value for money. The 36″ wide x 15″ long x 16″ high tank is composed of acrylic material in a rectangular shape providing strength and support which cannot be shattered or chipped unlike glass counterparts.
The tank is built with a wide variety of uses in mind suitable for reef, marine, salt and freshwater setups. Sea Clear products are known for their exceptional quality which is the main focal point of this particular fish tank over other similar tanks. However, the pricing of this tank is a little higher than other competing tanks such that one would need to decide whether their budget would permit a slightly more expensive spend for the extra quality on offer.
Overall though, MyAquarium believes that the price to quality ratio and included hood does match up making this quite a good choice although the lack of accessories which one might find in a starter pack do make this less appealing to the beginner aquarist. The product also comes with a limited lifetime warranty epitomising just how seriously SeaClear view the quality of their products. This particular acrylic tank is also more suitable for a warmer ecosystem since acrylic has much higher heat retention than glass although some aquatic enthusiasts believe it discolors.
However, MyAquarium’s extensive testing along with consumer comments shows that the SeaClear product in particular does not discolor even after long term use quite possibly due to the quality raw materials SeaClear uses to produce their tanks. Overall, the SeaClear 40 gallon tank is a good medium sized tank, one of the better acrylic offerings and excellent for existing aquarists who are just looking for a new, good quality tank without any accessories or extras.

It is a standard rectangular shape with similar dimensions to other 40 gallon tanks and the glass is of high quality. However, with all glass tanks there is a risk of cracking over time thus acrylic tanks are generally more durable yet have their own downfalls as well.
The Top Fin 40 gallon fish tank is quite good value with a reasonable price point for beginners or professionals looking for a new tank. It does come with a black trimmed hood as standard with a fitting for a fluorescent light sold separately.

Overall, even if one was to purchase all the required accessories separately, total outlay would still be less than some of the more overpriced tanks on the market. In order for use with reptiles the fluorescent light fitting could still be used simply by placing a UV light in the fitting instead making it convenient for use in both niches.
