Is the aquarium glass or acrylic?

It is an acrylic tank but it's super thin so you need to treat it like glass (but it will still take a beating).

he lens on the Replacement Door appears to be the same material as the door and the enclosure housing. I would guess that it is acrylic.

glass. and they are very fragile. I bought 4 as Christmas gifts and there is only 1 surviving as of today. I would not recommend these for small children.

Now that I own one of these and have looked at it more closely. It should work fine on acrylic, but the earlier answer is nonsense. These thermometers peel and stick to the outside of the tank. There's labeling on the front of the package stating it goes on the outside. They're based on liquid crystal, which is generally nontoxic and non-corrosive. They pose no threat to fish, particularly since they don't go in the tank at all. I use it on a glass tank, but there's no reason these would not work on acrylic. Acrylic is a bit less thermally conductive than glass, so the thermometer will respond slightly slower to changes in temperature than it would on glass, but this shouldn't be an issue for day-to-day temperature monitoring or hour-by-hour thermostat adjustments. The only possible realistic drawback I can think of for acrylic is the peel-and-stick adhesive is designed to be removable, but it might be harder to remove from acrylic than glass. Having not tried it on acrylic I can only theorize.

plastic - Plexiglas would be my guess - pretty durable. I am pretty careful during cleaning to only use soft materials against the "glass" panels so I don't scratch them.

It is made of a crystal clear plastic, probably acrylic, which has a great, distortion-free reflection and is way safer in the shower. Also, it seems quite light, durable and easily defogged. Before this I probably would have insisted on glass. Buy it and I'm pretty certain you'll love it.

I believe it is acrylic. It is not tempered glass. I doubt you would be happy with glass as it is heavy enough as it is.

Acrylic to the best of my knowledge. Too sturdy to be plastic in my opinion.

Im not sure but I think its acrylic. It seems thick, but I dont think its glass.

They're plastic acrylic but look quite like glass or crystal when hung especially when the light is on

It is plastic but a very stong acrylic. Mine has never leaked or cracked and it is very clear.

It's acrylic. Obviously of good quality since it hasn't etched or marked since we got ours a long while ago.

They are a clear acrylic. They are solid (not rubbery). I use them for beads and crystals and they work great. The lids are secure but easy to remove when needed.

Acrylic, I think. Would not recommend them. They break easily. I have 0 left.

I'm not a scientist, but for the aquarium, the acrylic it's made of is great. The tank cleans well, looks beautiful, and there have been no leaks in the years I've had it.

Glass. But the one I bought for my parents has broken within a year. Disappointed

It is plastic, very cute tank and the perfect size for a betta or other small fish. The filter isn't much to brag but other than that it's a great little tank.
