Aquarium driftwood

Adding driftwood to your aquarium adds décor while giving your fish places to hide and rest. It’s no wonder that this wood is such a popular choice among fish owners when creating their aquascapes. The problem is these pieces of wood can sometimes be too small. Other times, they float to the top of the tank. You could craft a few pieces together to form a larger structure while also giving your fish something fun and entertaining to swim through. But how can you attach driftwood pieces together? Can you attach pieces of driftwood to glass?

  • The 6 Best Glues for Driftwood Are:

    1. Seachem Flourish Glue — Best Overall

    Seachem Flourish Glue

    Check Price on Chewy
    Water Type Fresh or saltwater
    Bonding Time Within seconds

    Our best overall choice for driftwood glue is Seachem Flourish Glue. This gel is used for attaching moss and other aquatic plants to driftwood and other surfaces, including gravel. It can be used underwater and is suitable for fresh or saltwater tanks. This is a versatile glue that helps add beauty to your tank and dries within seconds.

    We like the metal tube packaging of the glue, but there are a few reports about the tubes leaking if you set them down while they’re open. The biggest complaint about this glue is that it dries white. If it dried clear, it would be less noticeable. Overall, though, it’s the best choice for your fish tank adhesive needs.

    Pros
    • Long-lasting
    • Easy to use
    Cons
    • Dries white
    • Tubes leak

    2. Instant Ocean HoldFast Epoxy Stick — Best Value

    Instant Ocean HoldFast Epoxy Stick

    Water Type Fresh or saltwater
    Bonding Time 7–30 minutes

    Our best value driftwood glue choice for the money is Instant Ocean HoldFast Epoxy Stick. The epoxy is non-toxic and safe for all fish and other animals, including reptiles. The surfaces that you’re putting this on must be dry before you use it. Just rub a bit of the product between your fingers until it turns white, and you’re ready to shape this adhesive to whatever item you like. It takes 7 minutes for this epoxy to start to harden and 30 minutes before it’s fully dry. It dries white, though. The good part is that you can scrape, sand, or drill the dried epoxy until it suits your taste, smoothing it down until it’s flush with the objects that it’s securing.

    Pros
    • Easy to use
    • Affordable
    • Flexible enough to be used in multiple ways
    Cons
    • Takes a long time to dry
    • Can be messy
    • Won’t work unless surfaces are completely dry

    3. RA AquaTech Aquarium Glue — Premium Choice

    RA AquaTech Aquarium Glue

    Water Type Fresh or saltwater
    Bonding Time Within seconds

    Our premium choice is RA AquaTech Aquarium Glue. Four tubes come in the package, making this a good value. While the glue itself is fast-drying, it hardens instantly when it touches water. The package states that the glue dries green, making it an ideal choice for gluing plants to surfaces like driftwood. Other reports say that the color is actually closer to turquoise. This glue will start to bond after holding the desired glued piece to a surface for 20 seconds. While it may not be strong enough to hold pieces of driftwood together, it’s ideal for gluing plants or moss to your driftwood’s surface.

    Pros
    • Dries quickly
    • Turns green when dry
    Cons
    • Messy
    • Works best when applied outside of the tank

    4. Guoelephant Aquascape Glue

    Guoelephant Aquarium Glue

    Water Type Fresh or saltwater
    Bonding Time Within seconds

    The Guoelephant Aquascape Glue dries black, enabling it to blend in with the surroundings and not be noticed when by anyone admiring your aquarium. This is acceptable glue for fresh and saltwater use and can be applied underwater. It works well to attach plants and decorations to rocks and driftwood in your tank. It’s not toxic to any aquatic animals or plants. You receive two tubes of glue in this package, and the shelf life of the product is 12 months. This glue can attach items to driftwood, but it also works well for coral, shells, moss, and stones.

    Pros
    • Turns black when dry
    • Dries quickly
    Cons
    • Can be messy

    5. Landum Aquarium Glue

    LANDUM Water Plants Glue

    Water Type Fresh or saltwater
    Bonding Time Within seconds

    The small tube can be misleading, but a little goes a long way with this Landum Aquarium Glue. This product turns to a gel consistency in the water, so you have a little time to place things where you want before the glue dries completely. It will also dry on your fingers, so wearing gloves is recommended when using this. It works on various underwater decorations, including coral and stone. This glue doesn’t harm any aquatic plants. It’s also a good option for attaching moss to driftwood. There are a few reports of white spots appearing on the glue as it dries, but these are said to disappear over time.

    Pros
    • A little goes a long way
    • Has many uses besides driftwood
    Cons
    • Might stick to fingers

    6. The Original Super Glue Gel

    Super Glue

    Water Type Fresh or saltwater
    Bonding Time Within seconds

    The Original Super Glue Gel is a perfect choice for aquariums. Not only does it start to cure the second that it touches water, but the gel is a little thicker than regular super glue and easier to manipulate on surfaces. This is also a good choice for porous surfaces. It bonds within 30 seconds and is handy to have on hand for things outside of the fish tank too. There are reports of frustratingly hard-to-open packaging, but once you do get it open, there are 12 tubes of glue inside. If you like to change your aquarium decorations around regularly, this pack will give you enough glue to work with for a while.

    Pros
    • Dries quickly
    • The gel formula is easy to use
    Cons
    • Packaging is poorly designed

    Buyer’s Guide: Choosing the Best Glues for Driftwood

    Strategically placing your decorations in your aquarium is a delicate process, and walking by later to see that they’ve all come loose and are floating around the tank can be frustrating. Weighing or tying them down may work in the short term, but a more permanent solution is to glue them.

    Finding the perfect glue for your aquarium will depend on your needs. When it comes to driftwood, you need an adhesive that’s easy to work with and flexible enough to fit the wood’s crevices and pores.

    Super Glue Gel

    This is great for driftwood because unlike thinner glues, it won’t run and make a mess. You are better able to shape the gel to the surface that you’re using. With driftwood, the gel can easily be maneuvered over the different contours and shapes of the branches. It has a cyanoacrylate base, which is safe for aquatic animals. It’s also a cheaper option than some other adhesives. Super glue gel usually dries white, which is important to know if you don’t want it showing between the adhered surfaces.

    Silicone

    Silicone glues aren’t always aquarium-safe, so it’s important to check that the one that you choose is non-toxic to aquatic life. Silicone adhesives are chosen for their flexibility once dried. They still offer a strong hold and most dry completely clear, which is an appealing feature. You can also choose silicone adhesives that dry in different colors to match your décor. This product should be fully dry before you submerge it in water.

    Epoxy

    An epoxy adhesive has a clay consistency and is easy to use underwater, so it appeals to people who want to decorate without taking everything out of their tanks and waiting for them to dry. That process can be daunting. Epoxy is also easy to shape and mold, so you can create caves, steps, and more to entertain your fish. To use, rub a bit of product in your fingers to soften and activate it. Then, place it where you need it and let the decorating begin!

    Doesn’t Super Glue Hurt Fish?

    Dried super glue does not release chemicals into the water. It’s waterproof once it has fully cured, making it a popular option for aquarium use. A 100% cyanoacrylate super glue is safe for aquatic animals once dry.
