OverviewThe Arrowhead Puffer (Tetraodon suvattii), also known as the Pig nose or Mekong Puffer, is a unique freshwater pufferfish known for its distinctive wedge-shaped head and ambush predatory behavior. This species is highly territorial and best suited for experienced aquarists who can meet its specialised care needs. Unlike more active puffers, the Arrowhead Puffer prefers to remain motionless, often burrowing in the substrate to lie in wait for unsuspecting prey.
Origin
Native to Southeast Asia, particularly Thailand, Laos, and Cambodia, the Arrowhead Puffer is found in slow-moving waters of the Mekong River basin. It thrives in muddy or sandy riverbeds, where it uses its camouflage and hunting instincts to capture live prey.
Feeding
This species is a strict carnivore and requires a diet of meaty foods such as:
Live or frozen shrimp
Snails (important for maintaining dental health)
Small fish
Worms (bloodworms, earthworms)
Crayfish or other crustaceans
Due to their ambush predatory nature, they will often ignore dried or processed foods, making a varied diet of fresh or frozen items essential.
Tank Mates
The Arrowhead Puffer is a solitary species and should be kept in a species-only setup. It is highly aggressive and will attack or kill tank mates, including other puffers. If attempting a cohabitation setup, it must be with extreme caution and in a very large, well-structured tank, though it is generally not advised.
Aggression
This species is one of the most aggressive puffers available in the aquarium trade. It will attack anything that enters its territory, including other fish and even human hands during tank maintenance. Due to its powerful bite and territorial nature, caution is needed when handling or interacting with the fish.
Experience Level
Advanced – The Arrowhead Puffer is not recommended for beginners due to its aggressive nature, specific feeding requirements, and need for careful tank maintenance. Aquarists should have experience with predatory fish and species that require specialised care.
Water Parameters
Temperature: 24-28°C (75-82°F)
pH: 6.5-7.5
Hardness: 5-15 dGH
Tank Size: Minimum 40 gallons for a single specimen
Filtration: Strong filtration with low flow (prefers still waters)
Substrate: Sandy or fine gravel (to allow for burrowing)
Decor: Driftwood, rocks, and caves for hiding
Conclusion
The Arrowhead Puffer is a fascinating but demanding fish best suited for a dedicated aquarist who can accommodate its predatory instincts, aggressive nature, and dietary requirements. With the right care, it can be a rewarding and impressive centrepiece fish in a specialised setup.

Unbelievable toy for aggressive chewers
Color: Green Cactus
Great toy for aggressive chewers! I'm not one to hand out 5 star reviews but this one I 100% believe in. I bought the first one in 2023 and just replaced it because it broke. Now this is not a played with every once in a while, this was played with daily as it is his favorite toy. Very few toys last long but this one has went beyond my expectations. Could not be happier.

Not Recommended!
Color: Green Cactus
Be aware that with major chewers it is not durable. My dog tour right through it and was eating pieces off of it. Thankfully we got the pieces back out of his mouth but definitely not for tough chewers. Also only lasted 2 days in decent condition and was only used on the occasion throughout the day.

Not strong lasting
Color: Green Cactus
Didn’t even last 3 hours in my house. Too rubbery and our frenchie mix was able to bite pieces off and was trying to eat them. Don’t recommend as a super chewer or consider it durable

Very durable!
Color: Pink Cactus
One of the few actually tough chew toys for dogs who tear apart toys in seconds! My dog loves this thing and has yet to break into the rubber!

Great product! Durable, chewable, awesomeness!
Color: Grilled color, Color: Grilled color
Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!
