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 Lovely Tank! We have had this tank for about five years. We have received compliments on it numerous times. The seamless, half-moon shape is beautiful. Marineland customer service has been very helpful and nice, as well.

Rated 5 out of 5 by from Absolutely love how this showcases the fish! (30g) I purchased the 30 gallon size, and could not be happier. The fish are showcased so nicely in this layout. The stand was damaged by the store, which got me thinking after they offered a discount. As a woodworker, my wheels started turning. I had recently cut down an ash tree dying from an emerald ash borer infestation. I covered the stand in the ash wood, then cut the bark off the tree and covered the base and a hood I fashioned for it. Yes, I would love it without my upgrades, but I'm ecstatic how it turned out afterwards. I highly recommend this tank!

Rated 5 out of 5 by from Sharp tank This is a *really* nice looking tank. The effect of the curved front is quite impressive; and, as others have noted, gives the effect of a larger aquarium. The rimless top also gives a very clean appearance.Definitely get the 30-gallon over the 20-gallon version if you can. The footprint of the 30-gallon fits the stand perfectly; and you're unlikely to regret the extra volume.The included LED light is adequate for some fish; but, if you want to grow plants (or just about anything else photosynthetic and desirable), expect to purchase a separate light.The included acrylic top has a well where the included LED fixture sits; if you use a different light, you will probably want to dispense with this cover, as well.The weak link in this setup is the stand Marineland makes for this tank; but that's a separate listing (and a separate review). Just be advised that if you want a stand with enclosed storage, you'll probably need to build it yourself.

Rated 5 out of 5 by from I just purchased the 20 Gallon Half Moon Aquarium with Day/Night Led Lighting and compatable Stand I bought this aquarium from only looking at the picture of it online and I was a bit nervous about that. I picked it up from the dealer today and I am so pleasantly surprised. The stand is well made and sturdy, The Tank is just beautiful! It gives the appearance of being larger than a 20 gallon, The light strip fits snugly in to the bracket.. the cut outs for the power filter and heater are already in...no cutting needed.. I LOVE this tank..It is a real beauty!

Rated 4 out of 5 by from great tank but not so great canopy I just purchased a 30 gallon half moon tank, and I love it. It provides a great view of my fish. I am also using a fluvac canister filtration system as opposed to the recommended filter system. I would like to see a different lid for this tank as it is not very practical for cleaning, and if you balance the light on the corners it is a very real possibility that it will fall in the tank. I would encourage the company to try and explore a different lid for this tank, I would buy it in a heartbeat.

Rated 5 out of 5 by from Very nice product It is very nice, the only problem was we spent more time taking the tape residue off of the glass. otherwise it has turned out very pretty and soothing.

Rated 5 out of 5 by from awesome customer service I had purchased the 30g half moon combo package at my LFS. Upon attempting to clean the plastic lid, I cracked it. Customer service was quick , friendly and very professional. Since they don't sell a replacement, they offered to send me another lid free of charge. This company really stands behind its products. Thanks again

We do not measure the lumens; we do measure Kelvin. This light is only 5500 Kelvin and would not be suitable for live plants.BREX

I was thinking about buying the Half Moon Aquarium but after reading these reviews they seem to have a common theme of the top cover cracking or becoming damaged or cracks in the glass somewhere along the bottom? Why is this so common?

Asked by: Golfchic
Cracks across the bottom are not very common, compared to the numbers of these tanks that we sell. The main reasons for cover damage are getting stepped on a lot, dropped or damaged from rough handling for some reason. BREX
