  • Cavern for Shelter, Hiding, And Swimming --- Beyond aesthetic enhancement, Resin Cave by SunGrow serves as a haven for fish when they need a place to rest and hide. This also invigorates your aquatic pets when they swim through this arch because this functional décor makes their ambiance more interesting.
  • Relieve Stress and Comforts Fish --- Most fish are at ease if they have a place of their own where they can easily go for hiding when they feel threatened. This personal space gives them a feeling of security as they drift away from their stress triggers whether real or imagined.
  • Creates Attractive and Real-looking Aquarium --- This resin ornament with its gray color and green mossy highlights gives a realistic appeal to your tank. Such an ambience will not only enhance your pet’s habitat physically, but it will also be visually appealing and advantageous for aquarium fish. The realistic underwater environment will always make them feel at ease and will help them to act normally.
  • Give Them the Hang of Real-looking Rock --- This resin décor works like a real rock in your fish habitat. It doesn’t affect the water condition as it doesn’t release pH altering elements. This ornament doesn’t have sharp or rough edges that will cause cuts to your beloved fish fins.
  • Color-stay & Sturdy Material --- Even when soaked, its color will remain the same and won’t fade. It can stand steadily underwater. This decor won’t be shaken by water currents, your aquatic pets’ aggressiveness, or lighting. But before placing it in the aquarium, we recommend soaking the cave in a lukewarm water bowl for 5 minutes, air dry and then adding it to fish tank for them to enjoy.


Product Description

The Struggle is Real

The difficulty of setting up a perfect tank doesn’t just stop at setting up filtration apparatus and/or fish you want in your collection. Even if you have your water quality test kit ready, what’s really mind-boggling and time-consuming is decorating your aquarium. When it comes to creativity, the sky is truly the limit. In this dilemma, you are sometimes torn between visual appeal and functional properties.

What Matters Most

However, one very important consideration in making the decision is the pet’s well-being. People are sometimes allured by all the cute decorations they see anywhere. Sadly, some also end up adding things that are not designed to go in fish tanks. Decorations with sharp edges, copper, real coral, driftwood, concrete, and painted plastics should not be inside your aquarium.

Please note that these items may cause problems. Sharp edges can easily harm your fish and paint on plastic can flake off. Real corals and driftwoods are also not advisable. Copper, on the other hand, can alter water parameters adversely.

Think Tank and Beyond

Resin Cave by SunGrow is the perfect addition to your tank as it is decoratively functional and more importantly, will keep your aquatic inhabitants guarded. It is specifically designed to be in fish tanks and rest assured that materials used won’t deteriorate when submerged in water for a long time.

Suitable for both fresh and saltwater aquariums, this realistic moss cave provides a real-looking aquascape to your tank. Nocturnal fishes will enjoy it as a daytime shelter while other small fishes can swim through it. Other tank dwellers such as crayfish, shrimps, or aquatic frogs can use this as a place for hiding, resting, sleeping and simply having fun.

How to Use:

Before using this, kindly clear with a brush in cold water for about 2-3 times to remove grass debris, dirt, and impurities. Then soak the resin cave for 5-minutes in a bowl of lukewarm water. Make it a habit to clear it once a week to avoid proliferation.

This medium option is in my 5 gallon tank. It arrived well packaged and seems to be made of a good material. Following some of the other reviews suggestions, I gave it a good rinse before putting into my tank and I haven't had any issues with green flakes. It's big and offers great shade for the Cory's and shrimp. The shrimp love to crawl all over and pick through the moss. I wish they had a smaller option but the medium is working well.

I liked it pretty well. The only few things to note (hence 4 stars instead of 5) if you are using this for any aquatic creatures with sensitive skin you will have to sand it down. There are so many sharp edges. You also have to scrub it down since the moss on it flakes off when you first open it and just rinsing it is not enough.

Although a great size and looks good, would you want this in with your betta or any other fish? It has a lot of sharp edges that need to be filed down. This is typical of a huge number of plastic decorations, so I expected it. But more to the point, I placed this in a bucket of clean water to rinse off before using in my aquarium. An hour later this is what I found. Needless to say, I won’t need to file the sharp edges. It will be returned.

Ok first and foremost this is a solid lizard hidey rock. Pretty, easy cleaning, sturdy all the things.However!!! I now have TWO leopard geckos due to this damn rock. Shortly after placing the rock in the tank, I walked by and noticed the lid was off and my 10year olds brand new pet lizard gone. We searched high and low, removing all tank items and BOOP gone. We figured our cat ate it and did what any good parents would do- replaced the lizard before she could notice.After several days, a new imposter gecko and not one kid any the wiser, we thought we were in the clear.Nay nay!On day three of imposter lizard, 10yo noticed the cage was extra poopy and set out to clean her pets area. WELL BOY GOLLY was she in for a surprise. She picked up the rock and scream MOM THERES A TAIL IN THE ROCK.**ensue panic** husband and I ran to the tank fearing found lizard parts. We did not in fact find any dead lizard parts, naaaaaay!! We found THE WHOLE ENTIRE FIRST LIZARD ALIVE STUCK IN THE ROCK. My husband had to carefully break the rock and PULL the very stuck little lizard out of it. OG gecko had been STUCK in the rock for nearly three days and maaaaaaan did we have some explaining to do.We now have a VERY happy two lizard having 10year old. And no rock.

My fish died before I recieved it but I plan on getting another beta and can't wait to use it. Its a good size and looks so cozy for the fish. Love the greenery on the top. My fish got fin rot because of what I was using before and he just could not survive the second time around. I decided the cave I was using was causing it. The edges on this cave are smooth and its big enough to turn around in without tearing the fins. I think it will be much better.

Wonderful cave for my Betta. He was at home in it immediately and it’s pretty. It does have some sharp edges. But I smoothed them out with an emery board. It’s functional, attractive, great price, arrived in perfect condition. Just take care of those few rough edges.
