I used this in my puffer fish tank. The tank was incredibly clean before putting this rock inside. Less than 1 week after the rock started to grow some type of mold. It quickly spread around the bottom of the rock and to nearby plants. The rock is cute and looked nice in the tank. I took it out cleaned the whole tank and put it back in the same thing happened again. Unfortunately I ended up taking the rock out again having to reclean the entire tank again and didnt put this rock structure back in. My puffer did enjoy swimming through the holes in the rock to hunt shrimp.

This is a great addition to an aquarium! The realistic stone appearance, natural coloring, and detailed rock textures give it an authentic look. I especially like the stacked stone design and the openings that create interesting spaces for fish to explore and swim through. The resin construction is another nice feature, providing the appearance of natural rock without using actual stacked stones. It's an attractive decoration that adds character and dimension to an aquarium. Overall, I'm very pleased with the design and appearance and would definitely recommend it! I received this product for free from the Spotted by Petco sampling program in exchange for my honest review.

The Imagitarium Resin Stone Stack fits great in my aquarium. I have a Beta fish, Mr. Lincoln and a snail, Gary, they appear to like the added "attraction". The stone stack adds a little bit of interest to my tank.

This Imagitarium Resin Stone Stack is so great. I love this for decorating within the aquarium. This can also be used outside for flameless candles too. I love how natural this looks and my fish seem to enjoy it too.

This little rock formation is absolutely perfect for my 10 gallon tank. It's just the right size, and the fish love to swim through and around it. In a larger tank, however, it would probably look quite small.

I’m only giving this 5 starts because it’s a great size, it’s exactly what I was hoping for, and I appreciate the person who helped me from customer service, BUT unfortunately whoever packaged it just threw it in the box and put the bubble wrap on top of the item instead of wrapping it around it. Of course since they carelessly packaged it that way, it arrived broken. This is why I had been so hesitant to order these types of fragile items online since I’ve read MANY reviews on similar items that were received broken. You’d think by now they’d be told to wrap the bubble wrap or SOMETHING around the item because of all the reviews about this happening and it’s also common sense. Petco please do better by training these people to package these things correctly! You’d save so much money in the long run because I’m sure you have to constantly replace items when you get the same complaint. I’m not only blaming the employees since it’s your responsibility to correct it! Maybe you need to come up with a different system. Other than that, the person who helped me from customer service was very helpful and automatically sent a replacement without having to return the item or doing anything difficult to be able to get a replacement which definitely made me feel better about the situation. I did appreciate that a lot. Hopefully the replacement doesn’t arrive broken I normally would never write a review because I don’t like to discourage others when I know there’s many benefits from having this store and it’s great to see when they do make it right by replacing things, but I can’t fathom why no ones taking any action to prevent this. Like I said DO BETTER and don’t ruin your business by not confronting something that can so easily be prevented. Rant over thanks.
