    • do you have a shy algae eater too? this is for you!
Color: Corner Tunnel, Black
I LOVE THIS THING! someone used a 3d printer to make it, but its perfect for our tank. our little algae eater loves going in it and hiding, but now we get to see him. Fit great in the tank, and a steal of a deal. definitely would repurchase and have thought about getting another to do both sides of the tank. ... show more

    • Sturdy but…
Color: Corner Tunnel, Black
Review Image by Marcia
The piece is rather sturdy, and was exactly as described and expected. However, because of the silicone in the corners of the tank, the piece would not sit completely flush against the glass walls, and therefore sand would sift down into the tunnel. My kuhli loaches have been seen in there several times since yesterdays installation but the tunnel is filling up quickly with sand and I’ve even witnessed them squeezing between the glass and the tunnel to enter. I will likely get one that sits flush against one wall of glass rather than a corner piece, even though I really loved the idea of the corner. Installation was a bit tedious, since my tank was already established and aquascaped, so I would recommend installing before adding substrate, if possible. Not a total waste but not likely to use for long. I gave 3 stars because although the piece is well constructed, the design is flawed, as I would imagine most standard aquariums will have silicone in the corners. ... show more

    • Cool concept
Color: Corner Tunnel, Black
I got this as a place for my shrimp and others to hide away from the betta. Tough luck, betta swims through it too lol. Nevertheless the Corys, snails and shrimps still find their way in there and hang out. I think it's a cool hidey-corner where you can still see who's in there. Good addition to the decor. ... show more

    • Cutting edges! Also, way smaller than It shows.
Color: Corner Tunnel, Black
This product shows it to be pretty good sized. the picture is way wrong. I got this for my plecos to hide and maybe use as a breeding tunnel, but my plecos that can breed would not even get in it. Maybe the babies can use it, but not if they get over an inch long. Very Disappointed at this purchase. Will not buy again! ... show more

Originally purchased as a Christmas gift for my son's salt-water aquarium so that his shrimp could hide from the starfish and clownfish. But the shrimp didn't make it. So he placed it in his 9 gallon (I believe its 9) fresh-water aquarium for his zig-zag eel and within mere seconds...and I'm not embellishing...that eel was in the tunnel and LOVING IT! Ingenious invention! I'll see if I can take better images because the color of the tunnel and the rocks are both black and difficult to see. ... show more
