Chatelet REEFSHAPE Aquarium Corner Tube Viewing Tunnel | Fish, Shrimp, Loaches Hideout for Aquariums | Unique Underground Tube Viewing Tunnel | Made in USA (Corner Tube, Black)

(FYI: some of my photos are flash enhanced)I definitely & happily recommend these cave enhancements for your aquarium, if you are looking to add "territory" to your aqua-landscape without added clutter. I have been very pleased with these so far!After shopping around the internet for some sort of sub-level space adding structure for my 45-tall tank, I settled on trying these "caves." I like how these unique add-ons have enhanced my enjoyment of watching my fish. They are a nice aesthetic enhancement that has proven to be quite the attention-getter / conversation starter for my guests stopping over and noticing my tank. The crew putting in my new heating system (known for their efficient in-and-out approach to jobs they have done for me in the past) found themselves taking a good 15-20 look at my setup! I was assured that time was "off the clock!"My full-bodied Bristol-nosed Pleco and Farlowela (stick catfish) species typically max out at around 6 to 7 inches, and they can navigate these caves with ease. Not only do these structures provide essential "defendable territory" for them as they assert their claim on tank real estate, but they also keep your tank looking neat without overcrowding it with decor.The smooth curves of these caves make it easy for them to enter or exit, especially if one decides to assert dominance in an already occupied cave. The 90-degree types I tried did not work well at all in this aspect.I was concerned that the sharper edges at the entrances might have been a safety issue. However, after over a month of use, I haven’t noticed any injuries being caused to my little tenants.Putting two of these caves in my tank - one in each front corner - has allowed my fish to feel securely hidden, reducing stress and preventing them from panicking every time I approach the tank to observe them. Even my Panda Corydoras, from infant to fully grown, appreciate these caves. They may be a bit more skittish, but the added sense of security encourages them to explore comfortably and not run off as soon as I close in to take a look.

The media could not be loaded. My betta fish absolutely loves it! But I gave it four stars since it did arrive broken. Other than that it was great!😁

I have no idea what the pictures are trying to show but that’s not how you use it. This tunnel is great for my fish only thing is I wish I didn’t get white as it gets dirty fast. And it’s annoying to take it out and back it, you must move all substrate in the corner to get it to fit perfect.

Print errors made it super sharp to the point I was worried about my fish. Seems sturdy and fits my tank with rounded corners. Just make sure you have sand paper on hand for this junk...

Love this, but make sure you get it in before you put in sand... cause I made a mess trying to get it in.... but it looks so cool, and fun to see my fishes dive in and pop out the other side.

Love seeing my fish enjoy going underground. Adds something unique to my aquarium, easy to install.

Just got it today and am not very happy with how it looks in my tank. I wanted it to go under the sand and it really doesn’t.

It came with rough edges I had to sand, but after installed my khuli loaches are always in it. It is hard to scoop an unsliced fish out though :/
