Plecoceramics Ceramic Magma Boulder Stone Decoration - Aquarium Fish Tank Hideway Decor - for Cichlids Plecos Bettas

Great entertainment for the fish with lots of holes to maneuver in and out of.

This is a nice little cave-like system that is great for fish that prefer that kind of setup. I threw it in my sons 20-gallon tank and so far its been a nice little addition. The only issue I have with it is the fact its a bit on the large size! While Im not a huge fan of this thing in a 20 gallon, this would be perfect for a 36 gallon or larger! Im going to end up moving it when I find something better, but in the meantime, this is really nice. His tank has plecos and I hear they love those structures. Well see. I dont really see his tank all that often, but when I go up, theres always something hanging out. Seems very sturdy and I made sure to boil it first just in case. No issues.

Exactly what I expected from the description.

Beautiful pleco cave with some nice detailing. I centered this in my tank for my pleco baby to claim as his own. Its a popular hangout for him, the betta sorority and my giant apple snail. Everyone loves the cave, and I will definitely purchase more of these for other tanks.

Finally! This Magma Boulder decoration is perfect for my 5-gallon fish tank and Karl just loves it. Just rinse well and drop it in. Ive tried multiple cubby holes from Amazon and the pet store but the paint chipped off, they attracted mold like a magnet and had a lot of sharp edges that needed to be sanded down to protect your fish. They all looked like some cheap plaster project we all made as kids in elementary. This decoration is solid, well-made, very smooth in and out, and looks great as part of a natural habitat for your fish. I cant recommend it enough.

We had a new fish that just loves to hide. We needed a place for him that the larger fish couldnt get into and this worked like a charm.

I’ve been looking for the perfect size cave for my 5 gallon betta tank for years. They are either too big or too small. This one is the perfect size. It’s made of ceramic and not plastic which I appreciate. There were no sharp edges to harm fins, so I just rinsed and added it to the tank. My fish explored it almost immediately.

Im not sure what thickness has to do with this product. I rinse it off in cold water for about a minute or more. It isnt smooth but a bit textured, like pottery before being glazed. When I put it into my fish tank, it started to release something into the water, like tiny bubbles of something. I thought odd, left it for a minute thinking it will calm down. It didnt. I pulled it out. Within 15 mins my filter light started blinking, meaning change the filter. This was after only 24hrs in use. It definitely had to be changed. I take it as that decor mucked up the water. Within 8 hours of putting this decor in, one of my Mollies died & the other 2 were struggling. The 2 struggling ones are doing fine now.

Easy to clean, never fades, and doesnt introduce particles or flakes in the water. Great price and solid material.
