Pincushion Sea Urchin – Lytechinus variegatusOverview:
The Pincushion Sea Urchin is a small to medium-sized urchin with a round, ball-like body covered in short, stubby spines. It gets its name from its pincushion-like shape. Known for being efficient algae grazers, they are popular in aquariums for keeping live rock clean.
Origin:
Found throughout the Western Atlantic, Caribbean, and Gulf of Mexico, often in seagrass beds, sandy flats, and shallow reefs.
Feeding:
- Primarily herbivorous: feeds on film algae, coralline algae, and macroalgae.
- Will graze constantly on live rock surfaces.
- Can be supplemented with dried seaweed (nori), spirulina, and algae wafers.
Tank Mates:
- Reef-safe (does not harm corals).
- Avoid predators like triggerfish, puffers, and large wrasses, which may nip at or consume them.
Aggression Level:
Peaceful. May accidentally knock over loose corals or frags while grazing and moving around.
Experience Level:
Beginner to Intermediate. Fairly hardy but needs a mature tank with sufficient algae to prevent starvation.
Water Parameters:
- Temperature: 72–78°F (22–26°C)
- pH: 8.1–8.4
- Salinity: 1.023–1.025
- Tank Size: 30+ gallons
Unique Features:
- Rounded “pincushion” shape with spines shorter and blunter than many other urchins.
- Known to decorate itself by attaching shells, bits of rubble, or algae to its spines for camouflage.
- Active grazer that helps control nuisance algae in reef aquariums.
‚ú® The Pincushion Sea Urchin is a hardy, reef-safe addition that excels at algae control and thrives in tanks with plenty of live rock and established algae growth.

Happy Doggo
Flavor Name: Beef, Size: Small
He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.

Excellent product, highly recommend
Flavor Name: Classic, Size: Large, Flavor Name: Classic, Size: Large
So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!

Dogs love them
Flavor Name: Beef, Size: Small
My two pups are power chewers. These bones are great! There’s no smell and pieces don’t come off like other bones. Although I am not a fan of the sound it makes when my dogs chew on them (nails on a chalkboard sound to me) they love them and it keeps them entertained. They are extremely hard so I limit their chew time (only because I can’t afford a trip to the vet if a tooth gets cracked) overall satisfied with my purchase, both myself and pups!

Excellent for heavy chewers!
Flavor Name: Beef, Size: Mini
My dog is between 1-2 years old, and is a heavy chewer. So far the Better Bone is lasting very well! He still is chewing away at it! Excellent quality, and I appreciate that there’s no plastic that my dog is consuming.

By far ... the SAFEST and most DURABLE bone for dogs that are hardy chewers!
Flavor Name: Beef, Size: Large
After searching high and low for a NON-TOXIC, DURABLE and truly SAFE dog bone, I finally found the large, beef-flavored, HARD version of the BetterBone for my year-plus-old rescue (Carolina Dog).
1 - it's made of all NATURAL food-grade materials (cellulose from plant cell walls) ... which means no nylon, no GMOs, and no other artificials materials so it doesn't event stain your flooring. My girl loves the tasty beef flavor.
2 - the wishbone DESIGN is genius because it gives her 3 ends to choose from (nubs v raised edges v smooth) and ample ways to stabilize it on the floor with her paws.
3 - it is uber DURABLE in standing up to the hardiest of chewers (my girl gnaws on hers daily and sometimes even multiple 10-minute sessions per day). It works great to clean and reduce tartar on her teeth. The biggest surprise was that it took 6 months for her to gnaw it down to a size that was no longer safe for her (i.e. a potential choking hazard), so I donated it to a lady with tiny dogs at the dog park. At $20 per large bone, it's a good value.
4 - and most importantly, ... it is super SAFE. It degrades in tiny little pieces that could not possibly cause a choking hazard, and being all natural (i.e. no nylon - which most bones do have), there is no worry if she does ingest some of the particles. They vacuum up with ease.
The large bone weighs in at just over 12 ounces so it's kinda' heavy (9.25" long x 5" wide x 2" thick), but my 56 lb girl has no problem picking it up in her mouth before she hops up on the couch with me or into her bed.
Thank you BetterBone for making a superior product that is healthy, safe and fun for my pup!
