Hydrolycus Armatus (Payara) Store DescriptionOverview:®The Hydrolycus Armatus, commonly known as the Payara or Vampire Tetra, is a striking predatory freshwater fish renowned for its elongated body, silver sheen, and long, fang-like teeth. With its ferocious appearance and fast swimming speed, this apex predator is a captivating addition to any advanced aquarium.
Origin:®Native to fast-flowing rivers of South America, particularly in the Amazon and Orinoco River basins, the Hydrolycus Armatus thrives in well-oxygenated waters with strong currents.
Feeding:®As a carnivorous predator, the Payara primarily feeds on live fish. In captivity, it may accept frozen or fresh fish but prefers live prey. A varied diet of meaty foods is essential for its health and vitality.
Tank Mates:®Due to its aggressive and territorial nature, tank mates should be chosen carefully. Ideal companions are other large, robust species that can withstand the Payara’s predatory instincts. Avoid smaller fish as they will be seen as prey.
Aggression:®The Hydrolycus Armatus is highly aggressive, especially during feeding. It may become territorial towards tank mates, especially those of similar size or appearance. Providing plenty of space and hiding areas can help minimize aggressive behavior.
Experience Level:®Recommended for experienced aquarists due to its size, specialized feeding requirements, and aggressive behavior. Maintaining the right water conditions and diet is crucial for its survival in captivity.

Slippery when wet!!!
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
“These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”

Love them
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.
