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 The best 30 gallon half moon tank on the market !! I built a custom modification to a shelf area to fit this perfect starter size tank. It is a centerpiece of our kitchen area. The circular view and tall size offers the best viewing area for tanks.

Rated 5 out of 5 by from They are AWESOME! Great Customer service I needed a lid for my 30 gallon half moon they quickly responded to my email and sent me a lid no questions asked and free of charge thanks so much you guys are a great company. At first I thought it was a 20 gallon tank and they sent a lid which was too small. I told them I told them the wrong size and I would buy a 30 gallon lid and they sent one free of charge. Now that is great customer service. I really appreciate their kindness and generosity.

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.

Can i drill this tank?

Asked by: ostas
This tank is not tempered. However, any drilling will void all warranty. BREX

I have this tank and am interested in drilling the bottom or back for my filtration. (I understand this will void the warranty.) Is the glass on the bottom and back tempered?

Asked by: SoberCannibal
Thank you for asking! You are correct that any modifications, like drilling the tank, will void the warranty. To answer your question there are no tempered panels. For more help call Marineland at 1-800-322-1266. We are happy to help.

Can I purchase the plastic canopy, the one I had was broken. I also need a new blackground. Are those available as well?

Asked by: Stephanie 79
The canopy is not available for sale, separately. I will email you though. We don't sell backgrounds. Those are available through local fish stores, www.thatpetplace.com and other vendors. You can buy them by the foot or by certain sizes. They come in colors like ocean blue or black or aquatic pictorials. BREX

Hello, I am looking to see where I can purchase a lid for my half-moon 30 gallon? The one I have is too small. 

Asked by: Chang234
This tank comes only as a kit, and the lid is not available separately. If you just purchased it, and it came with the wrong lid, please contact our Care Team at 1-800-322-1266. You may also email phgreviews@spectrumbrands.com. BREX

What type of glass are 70 gallons 1/2moon make of? Temper or regular glass. Thread on I ask is that I needed to drill 2 holes in the back of the tank. Thanks

Asked by: Leevantran
We do not make a 70 gallon size. We make a 10, 20, or 30 gallon. They are not tempered, but drilling will void the warranty on them. BREX

My led light is flickering is it getting ready to go out how do I order a replacement  it is on the 30 gallon half moon aquarium. Thanks!!!

Asked by: Jojo63
Flickering can be a wiring issue or an electrical issue with your outlet, if you are not plugged into a power strip with surge protection. It can also mean water got up into the light somehow. The light has a one year warranty so if you are still under warranty, call our Care Team at 1-800-322-1266. Please have your receipt handy for faster service. BREX

I purchased the 1/2moon tank i described in my previous question.  It came with a penguin 200 filter , 2 piece glass top, and a light strip.  All  Marineland.  How can my tank be bigger than than the one you described in your answer to my question?

Asked by: JoeK
The only possible answer I know of is that either it is not our tank or you measured it incorrectly. The measurements I provided were taken by our engineer and are completely accurate. BREX
