- Tank size: 50L+ recommended
- Difficulty: 🟡 Moderate
- Temperament: Peaceful
- Best kept: Groups (5+)
- Plant safe: Yes
Is this for you?
✔️ Good if:
- You want a slightly more unique corydoras species
- You have an established, stable aquarium
- You keep peaceful community fish
- You are comfortable maintaining water quality
❌ Avoid if:
- Your tank is newly set up or unstable

Why this fish?
Corydoras acutus is a more refined and less commonly seen corydoras species, valued for its sleek body shape and subtle contrast markings.
It offers the same peaceful nature and bottom-level activity as other corys, but is better suited to hobbyists with stable setups.
Common mistakes
- Adding them to immature tanks → higher stress and losses
- Keeping them alone instead of in a group
- Assuming they survive on leftover food
- Keeping them with aggressive or fast feeders
- Neglecting water quality stability
Care made simple
- Temperature: 22–26°C
- Diet: Sinking pellets, wafers, frozen foods
- Group size: 5+ recommended
- Substrate: Soft sand preferred
- Water: Clean, stable, well-maintained
Pair with
- Sinking cory pellets or wafers
- Fine sand substrate
- Driftwood and plants
- Peaceful tetra, rasbora, or nano fish
NTA Insight:
Compared to common corydoras, this species benefits more from stable water conditions. Most issues come from immature tanks rather than the fish itself.

FAQ
Is this a beginner fish?
It can be, but only in an established tank. It is less forgiving than common corydoras.
Can I keep just one?
No. Corydoras are social fish and should be kept in groups of at least 5.
Do they clean the tank?
No. They forage for food but still require proper feeding.
Do they need sand?
Soft sand is preferred to protect their barbels, though smooth substrate can also work.
What do they eat?
Sinking pellets, wafers, and frozen foods like bloodworms or brine shrimp.

Everything a Teething Puppy Could Need — Well-Thought-Out Kit
Size: X-Small, Color: Teething Bone
The Nylabone New Puppy Starter Kit is a solid all-in-one solution for the first few months of puppy ownership. It comes with multiple chew toys and bones designed specifically for teething puppies, and my little one took to them right away. The variety keeps him engaged, and I appreciate that each item is designed to be gentle on developing teeth while still satisfying his urge to chew.
What differentiates this kit from other puppy chew sets on Amazon is the thoughtful selection of textures and shapes. It’s clear these toys are designed to stimulate gums, promote healthy chewing habits, and even support dental care. I also like that everything is non-toxic and durable enough to survive a few enthusiastic chews.
The only reason I didn’t give 5 stars is that the kit might be a bit small for larger breeds, or for puppies that are particularly aggressive chewers. But for standard small to medium pups, it’s a fantastic starter kit that keeps both puppy and owner happy.
✅ Bottom line: A reliable, well-designed starter kit for teething puppies which is thoughtful, durable, and engaging. Makes a great gift for new puppy owners or a practical addition to your own puppy’s toy collection.

Chew
Size: X-Small, Color: Ring Bone
My dog loves this little chewy bone and it’s good for her teeth. That was very cheap on a sale. It’s worth giving it a try highly recommend it.

Chicken Flavor Good, But 🔄 Rotation-Resistant✖; Best for Simpler Chewers
Size: X-Small, Color: Ring Bone, Size: X-Small, Color: Ring Bone
🐾 Hi, I’m PVD; plush sophisticate, chew critic, and active curator of rotational toy relevance.
This ring bone and I never fully bonded. I sampled it maybe five times in my entire puppyhood before quietly returning it to the bin (with a single judgmental glance).
Still, it does have value for the right pup.
⭐ Why I originally wanted to love it:
✔️ XS size works well for very young puppies
✔️ Chicken flavor lasts impressively long
✔️ Freezing offers temporary gum relief
✔️ Durable and safe; no odd odors or shredding
🌀 Why it’s now a respectful 3-star chew in my rotation:
✘ Never became a go-to toy (5 uses max in my life)
✘ Ring shape felt awkward, not natural or chic; hard to grip and maneuver
✘ Texture too tame vs. nubs or detailed chew surfaces
✘ When I was smaller, I much preferred the Nylabone Baby Blue Bone Chew Toy with nubs (my personal classic), and have since matured into nightly Nylabone “Nubz” edible bones
This Ring Bone is Best For:
• Very young puppies with minimal chew preferences
• Dogs who like simple textures and circular shapes
• Those just starting enrichment chew play
• Freezer treat rotations (briefly)
🚫 Not ideal for: picky pups, advanced chewers, or dogs who analyze toy ergonomics (like myself).
📝 Final Re-Barks:
A strong, well-made chew, but lacked the intrigue to make my permanent rotation. Works for basic chew enjoyment; not for pups with elevated taste or toy ambition.

Puppy loves it!
Size: X-Large, Color: Teething Bone, Size: X-Large, Color: Teething Bone
My small puppy loves this bone! I originally purchased this for a larger dog, but my small 10 pound puppy loves it more. It’s good quality and a softer material for puppies!

A hit, but could be stronger
Size: Medium, Color: Ring Bone, Size: Medium, Color: Ring Bone
Gave this to my 11 week old pittie, and she did significant damage within 15 mins. She left a pile of chewed bits on the couch but thankfully didn't eat them. Definitely don't leave unsupervised.
That said, she LOVED it and it seemed to help her teething gums so, I'm still giving it a 4/5
