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.

Cute - change footbed please
Size: 8.5, Color: Dense Smoke
These are so comfy and fit my usually 8.5 foot great. It's the footbed of UGGs that I keep hoping they'll change. It's like our memory foam mattress - cushy and great UNTIL THE HEAT comes! Then it's a no for this hot 65 yo G'ma!

Super fun!
Size: 8.5, Color: Red Pepper
These are so fantastic! The color is amazing! It is a bit on the tomato-red side of the color-wheel. The fit is great. They are comfortable from the 1st step. Easy to walk in.

Love them
Size: 5.5, Color: Red Pepper
I have gotten so many compliments on these shoes! They’re true to size and comfortable. Because of the material feet might sweat easier if hot but they dry quick. Quality is great and the color looks good, it’s more of a orange/red color. I got a 5.5 size
