Usually ships in 1-2 business days from our fulfillment center

Cholla Wood is the dried husk of the Cholla Cactus and is a popular natural hardscape material for shrimp tanks, nano aquariums, terrariums, and reptile enclosures. Its hollow structure provides natural shelter for shrimp, fry, and other tiny critters.

Over time, Cholla Wood develops a natural biofilm that is readily grazed by shrimp and other microfauna. It can be used on its own, covered with aquatic mosses, terrarium mosses or paired with rhizome plants such as Bucephalandra and Anubias to create natural-looking logs.

Best For
- Shrimp aquariums
- Nano planted aquariums
- Fry and small fish shelter
- Moss-covered log-like hardscape
- Terrariums and reptile enclosures
- Tillandsia perch (air plants)

Natural Variation
Cholla Wood is a natural product and every piece is unique. Small variations in diameter, coloration, texture, and opening patterns are normal and part of what makes each piece one of a kind.

This listing includes 4" Cholla Wood. All hardscape sales are final unless an incorrect item has been received.

Wood You Just Sink Already? The Curious Case of Floating Driftwood

If you’ve ever added driftwood to your tank only to watch it bob right back up… don’t worry, you’re not alone. Almost all aquarium driftwood is buoyant because it’s been dry before reaching your aquascape. It just needs some time (and a little help) to stay submerged for your nature-style, forest or jungle tank.

If you fall into this category—we know—it sucks. Especially if you already spent a chunk of time working on your aquascape. The good news is that there are a few tried-and-true, aquarium-safe methods you can use that will keep your driftwood grounded from day one.

How to Prevent Floating Aquarium Wood

Natural Weights:
This is our main go-to for sinking pieces of aquarium driftwood. This method is great because it can be used on all sizes and it typically blends in better. First, design your scape and make sure everything is your liking. From here, you can take one of two routes:

Plant your aquarium first and place dense aquarium stones on top. Be careful not to crush any plants.
Hold off on planting and position your rocks on top of the driftwood

From here, it’s a test of patience. Usually, the stone will be ready to remove in roughly 2 weeks. You can test it by slowly lifting a stone and watching the driftwood. If you notice any movement, it isn’t ready. Put the rock back and let it soak to become fully waterlogged. Our favorite dense stones for this purpose are Seiryu Stone or Hakkai Stone. If you’re already using something heavy, go with the same type if you have extra. But, if you’re using something porous and lightweight like Lava Rock, it may not be suitable for holding down a large driftwood structure.

Secure or Wrap:
This is another common method that requires patience and a steady hand through the process. Natural weights can be added quickly, but securing or wrapping the driftwood in place will need some attention to detail (unless slight shifts in direction or angle don’t bother you). This suggestion can be time-consuming, but the results are worth it because there aren’t any eyesores in your aquascape at the end. As far as what you choose to “fasten” your layout with, we’ve tried a few things. Green or brown cotton / nylon thread works great as it blends in better with wood tones and aquatic plants. We’ve even used zipties. Not our best hour, but it got the job done and our scape didn’t float!

Glue it Together:
Yes, this is aquarium-safe. Is it natural? No. But, this method is becoming increasingly popular in the modern landscape of aquascaping. We turn to glue when we want to flood an aquarium after planting. There are some caveats with this one. Unlike the first two options, glue leaves residue that can be seen by the human eye. You’ll either need to use some elbow grease and a sharp scraper to remove it once everything is dry or you'll need to disguise it while you work. To do this, you’ll need your glue (use liquid cyanoacrylate for this), tissue paper, aquascaping tweezers and a colored substrate that matches your driftwood *optional. When your aquascape is just right and ready to be glued, follow these simple steps!

Step 1: Roll up small portions of the tissue paper between your fingers. Use your tweezers to wedge a piece into key gaps where your driftwood is either touching or connected.

Step 2: Use your tweezers to hold it in place and apply a small amount of liquid glue. Once it makes contact, a chemical reaction will take place and a little puff of smoke will appear. Make sure you avoid breathing it in or getting it in your eyes!

Step 3: Let it cure and voilà! Once you’ve finished, you’ll see how strong this method is. Test it by lifting and making sure the secondary piece is still connected.

Optional hot tip: Sprinkle your crushed substrate on top of the glue during the curing process to create a seamless blend. Take it a step further and add some aquarium rhizome plants when you’re finished. We like using Anubias, Bucephalandra and Java Ferns!

Boiling and Pre-Soaking:
Yes, you read right. If the driftwood pieces you have are smaller and can fit a standard 5 gallon bucket or even a large kitchen pot (make sure your people are okay with this one!), then you can boil the wood to waterlog it faster. We’ve done this with Manzanita Twig Wood before and had great success with it. Alternatively, fill any container that is large enough to fit your driftwood with water, and let it soak for 1-2 weeks for a fire-free option!

Not up for any of the previous suggestions? We still have you covered and offer driftwood that is pre-attached to natural slate stone or bonsai driftwood trees with lava rock bases. Beyond that, check out the Strata Pro series by Ultum Nature Systems. These are pre-made readyscapes that feature natural, real hardscape and are conveniently attached to heavy bases designed to fit nano tanks and standard sized aquariums. Give it a go if you’re looking for a float-free aquascape for your planted tank.

Beyond visuals, driftwood releases tannins with natural antifungal and antimicrobial properties. If the slight discoloration of water doesn’t bother you, tannins can contribute to better health and vitality for your tank inhabitants. If it does, it’s temporary and can also be removed quicker with water changes. Some biotope aquarium hobbyists love the discoloration and tannins as it replicates many of the natural habitats for tropical freshwater fish. To each their own!

Some of our favorite go-to woods include Malaysian Driftwood, Pacific Wood, and Spider Wood—each offering unique shapes and tones that work beautifully in planted setups.
