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 customer service and wonderful tank We absolutely love our Half Moon 30 gallon aquarium. It fits in our family room nicely and is not obtrusive. We are so thankful to customer service for helping us with our cracked lid. Would recommend to anyone who would like a larger aquarium that goes nicely with any decor.

Rated 5 out of 5 by from Works Grat as aFOWLR Tank All my friends love this tank so much better than a standard square and it looks way bigger than a 30 gallon because of the half-moon design. The Lid Is so so But everything else is great!

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.

Is there a warranty on your 30 gallon tanks? My first one lasted a couple of years and the seal started leaking.  I bought a new tank 17 months ago and the bottom glass cracked and leaked every where. 

Asked by: DFeel
Oh no, that is awful! We are very sorry to hear that, and yes, they do have a limited lifetime warranty on them as long as they are placed properly on a manufactured aquarium stand. Simply call our Care Team at 1-800-322-1266. BREX

hows the light on the 10 gallon half moon is it capable of growing basic plants like java ferns and crypt lutea

Asked by: woronko
No, it is for illumination only. I added a Marineland Advanced LED 18" to the tank by removing the legs and laying it on the canopy, and the two combined are growing anubias, and crypts for me. BREX

Where can I just by the stand? I have two of these aquariums and lost both stands due to my home flooding in Houston and I can't find any place that I can purchase 2 new stands. I've been looking for almost 2 months.

Asked by: Spikey
You may have to special order it. It is not usually stocked on its own. Item number is 35706. We see a lot of stores on our dealer list for your area. Scroll to the bottom of any page, and click on Buying Options then Dealer Locator. Enter your zip code. Ultimate Fish, Houston Aquatics, Fishland, Fish Gallery and Aquatic World should be able to help. Go to the front desk and explain you want to place a special order, you may need a manager to do this. They can get it if their distributor carries it. BREX

Do you ever plan on making a larger half moon tank? I have the 30g now and am considering getting another larger tank and would really like it to be a half moon.

Asked by: Jeff59
Not at this time, no. We have some curved tanks like the 38 Curve, but we are not doing any larger ones. BREX
