Reviews of the Best Betta Fish Caves

Check out my top choice and the other contenders.

SpringSmart Aquarium Hideaway Rock Cave 

This cute little cave is perfect for Bettas or other small aquatic pals. The ceramic material comes in a granite finish, so it looks natural among your plants and substrate

The SpringSmart Aquarium Hideaway Rock has two large holes – perfect for peeking into or swimming through – and is large enough inside for resting or sleeping the night away. 

This unit measures in at 3.5″ x 3.5″ x 3.35″ so it’s perfect for small habitats as well as spacious ones. 

This Betta cave does not have any sharp edges, will not chip, peel, or fade, and has not had any reports of foul odors. Although the company does recommend soaking it for 24 hours before adding it to your tank. 

Pros 

  • Great for smaller habitats
  • Large enough to swim through and to rest in
  • Natural appearance
  • No sharp edges
  • Will not fade or peel
  • Made of ceramic

Cons

  • Appears bigger in picture (3.5″ x 3.5″ x 3.35″)
  • Check for sharp edges before adding to the tank (may be due to the production process). 
  • Needs to be soaked before adding it to tank

Ameliade Aquarium Cave 

Available in different sizes, these Betta caves imitate natural stone even though they are made from ceramic. The cave rocks come with two ample holes (one on each side) and are great for swimming and playing through, or for taking a break inside.

The two-piece set is designed for stacking the smaller one on top, giving your Betta a two-storey deluxe cave for extra fun, “bunk-bed” sleeping, or you can use them separately to create more resting or playing areas. 

These rock-like decorations come in various sizes, so be sure to check out the measurements so you’re not disappointed when they arrive (the stackable set measures; sml – 3.3″ x 2.7″ x 2″, lrg – 4.3″ x 3.1″ x 2.1″). They are easy to clean, just wipe, rinse, and place them back into the tank. 

The only downfalls of the Ameliade brand rocks are that they may not stay stacked and some customers report the outside is gritty, but they were able to wipe it away or use a light sandpaper on the surface. 

Pros 

  • Available in one-piece (sml and med), two-piece, and skull
  • Large holes for swimming, playing and resting
  • Natural, rock-like appearance
  • Easy to clean
  • Ceramic

Cons

  • Exterior may be gritty
  • May have some sharper edges
  • Rocks may not stay stacked 

Plant Pot Aquarium Decor

Although not quite a cave, these Plant Pots make an excellent hang-out for your Betta fish or for adding live plants to your aquarium. 

They are made of crystal glass so you won’t have to worry about any sharp edges or chipping paint. They come equipped with two powerful suction cups to place anywhere in your tank. Each pot measures 2.4″ x 2″ x 2.8″ and is clear so you can see your Betta resting or playing inside of it. 

If you decide to put plants inside of these unique aquarium pots, they come with drain holes to help the roots aerate and for water circulation. 

All in all these glass “pots” would add interest to any size tank along with a fun, safe way for your Betta to explore, rest, and sleep. 

Pros

  • Made with crystal glass
  • Strong suction cups
  • Comes in a two-pack
  • No sharp edges
  • Great for live plants (drainage holes)

Cons

  • May not be well packaged
  • They are small (2.4″ x 2″ x 2.8″)

PINVNBY Rock Mountain Cave

Are you looking to add some pizzazz to your Betta habitat? Then look no further than this charming Rock Mountain Cave by PINVNBY. This colorful hideaway features decorative corals, shells, and other undersea details, along with four ample holes to swim through or just hang around in.

It’s made from high-quality resin and measures 6.3 inches tall by 4.7 inches wide. However, even though it is pretty, some customers have complained that areas of the cave are sharp. Please inspect your product for rough or sharp edges before adding to your Betta tank

The company also suggests soaking it for at least 30 minutes before adding it to the habitat. This helps remove any dust, dirt, or particles that may occur during storage and shipping. 

Pros

  • Colorful
  • Large enough for big tanks
  • Four holes for swimming through
  • Ample room for resting
  • Made from resin

Cons

  • May be too large for tanks under 10 gallons
  • May have rough or sharp edges
  • Needs to be soaked before using

SunGrow Betta Fish Cave

Made from real coconut, the SunGrow Betta Fish Cave will give your fish the privacy he craves and the natural beauty you want. The coconut dome roughly measures 3 inches high by 5 inches wide (there may be discrepancies between products) and comes with an arched opening for easy access – perfect for hiding, breeding, and exploring. 

The one downfall of having a natural coconut product in your habitat is that it will need to be boiled with a carbon bag before using. The company also wants customers to note that there is a naturally occurring hole in the top that may need to be blocked (depending on the size of your fish). 

Pros

  • Natural product
  • Great for hiding and swimming inside
  • Smooth handmade opening
  • Suitable for 5 gallons and up

Cons

  • Needs to be boiled first
  • May be some discrepancies in the size 
  • May need to block the naturally occurring hole on top of the cave

AQQA Aquarium Trunk

Made from resin but designed to look like a real underwater log, the AQQA Aquarium trunk is as beautiful as it is useful for your Betta fish habitat. 

This half log is made with purpose and intention to ensure there are no rough spots or sharp edges that can harm your Betta and other delicate fish. It’s the perfect place to rest or play and comes in two sizes to suit all tanks (sml: 6.1″ x 3.3″ x 2.1″ lrg: 8.2″ x 4.7″ x 2.5″).

We especially like the natural-looking top-knot on the log, the splash of green, and the realistic wood grain molding. The large hole is also a great feature and the unit is heavy enough to stay anchored to the bottom of the tank.

The main concern of some customers was that after time the paint did bubble and chip, so be on the lookout for this issue. 

Pros

  • Made with resin
  • No sharp edges
  • Natural look
  • Comes in two sizes
  • Has a side hole for playing and peeking

Cons

  • Paint may bubble and chip

Plecoceramics Aquarium Cave

With both a swim-through hole and a cave, this unit has everything your fishy friend will enjoy. Made from ceramic and available in two colors, the Plecoceramic Aquarium Cave measures 8.26″ x 3.1″ x 3.9″ so there’s ample playing and sleeping space.

The natural hues and gentle peaks of this Betta cave will make you feel like your tank has a small mountain range within its borders. It’s also simple enough to use – just rinse and place.

The one issue that may be a problem is the “Sandy” color option in this unit seems to be rougher in texture, while the Arctic Blue is smooth and safe for delicate fins. 

Pros

  • Natural appearance
  • Made from ceramic
  • Comes in two colors
  • Good size for 10-gallon tanks and over
  • Is both a cave and a swim hole

Cons

  • Sandy color option may have rough edges
  • Blue color option is higher priced

Saim Aquarium Hideaway Decoration

A sleek modern design is only the beginning of what the Saim Aquarium Hideaway has to offer. Made from aquarium-safe ceramic in a beautiful steel grey, this Betta cave is perfect for aquariums 5 gallons and up.

The base of this hideaway measures in at 4 inches and is 2.95 inches tall. The door is the perfect width for Betta fish at 2 inches wide and the fun top hole is 1.1 inch in diameter, so you won’t have to worry about your Betta getting stuck.

Another wonderful feature of this minimalist design is the smooth edges – no torn fins or injuries from this Betta cave. Plus, it’s super easy to clean.

Pros

  • Sleek and modern design
  • Made from ceramic
  • Two holes provide swim-through and lounging area
  • Easy to clean
  • No odour, no rough or sharp edges

Cons

  • Product may take some time to deliver due to being from China

Plecoceramics Cichlid Stone

If you have a bigger tank and are looking for a natural-looking rock cave, then the Plecoceramics Cichlid Stone might be for you. 

This aquarium decoration is made by firing clay at a very high temperature. It comes in several different styles and sizes, so be sure to check out the measurements so it will be the right fit. 

All the models come with two ample holes for swimming and playing, as well as a roomy interior for napping or hiding out. We are also happy to report that these products seem to be very smooth making them Betta-friendly.

The only downfall is there is no choice of color and also one customer mentioned a bit of an odor coming from the ornament, but soaking it did help reduce that issue. 

Pros

  • Made with ceramic
  • Available in many sizes and styles
  • Great for playing and resting
  • Two ample holes
  • Smooth, without any sharp areas

Cons

  • May have an odor
  • No choice of color, only size

Why Do Bettas Need Fish Caves?

Whether you’re adding a betta to an established tank (with other fish) or one they can call all their own, having a Betta cave is a good idea. 

Bettas love to explore, so giving them an appropriate decoration with holes to poke their heads in, or one that is large enough for them to swim through will help break up the boredom of their aquatic world.

Another reason to add a Betta cave to your aquarium is for a safe place for your fish to rest or to go to when he is feeling stressed – this is especially important in a community tank. Bettas also like to stake out territory, so you may notice that the Betta cave becomes part of his “home turf.”

How to Choose the Best Betta Cave

Before you purchase a Betta cave consider these points.

Sharp Edges. Even though aquarium decorations are made for fish, sometimes the molding process of the plastics and polymers can leave behind sharp edges that may injure your betta. If you have a decoration with a sharp edge, try sanding it down with sandpaper. 

Size of Cave vs Size of Tank. Using a large structure in a tiny aquarium will leave less swimming area for your Betta. Be sure the size of the cave is suitable for the size of your tank.

Hole Size. Are the holes in the structure suitable for a Betta? Will he get stuck going in or out, or get stuck inside the cave itself? Believe me, you do not want to have to get your fish out of a structure that is too small (it is stressful for all concerned) and can cause injury (or even death) to your Betta. 

Inferior Paint. We looked over products made for Bettas where the paint reportedly chipped off and some had a foul odor emitting from it. These are both signs of inferior construction. Only buy products that won’t chip or peel and the paint is suitable for being submerged into water. Bad paint can be toxic to your aquatic animals!

Stability. You don’t want a Betta cave that is supposed to stay put, floating around. Be sure the weight of the decoration is enough to keep it anchored. 

Final Thoughts on the Best Betta Cave

Betta fish need a space to call their own, even if they are the only members in their habitat. The perfect hideaway cave with appropriate-sized holes will be a welcomed addition for your Betta fish.

However, before you add any cave (or decoration) to your aquarium be sure that there are no rough surfaces or sharp edges that can tear those delicate fins or scrape his scales. 

We’ve done our due diligence in reviewing our top choices of Betta Caves, but remember to thoroughly inspect any decoration before you use it. Not all products are created equally (not even those from the same company or stock). We also want to remind you to rinse or soak your Betta caves (according to product instructions) and always remove any decor where there is a foul odor or the paint is peeling, bubbly, or chipping as these could prove to be hazardous to your aquatic pals. 

Giving your Betta the perfect cave to play in, swim through, and rest in is just one of the ways you can bring joy, happiest, peace, and health into his world.
