Freshwater Porcupine River Stingray Potamotrygon Hystrix 20cmOverview: The Freshwater Porcupine River Stingray, scientifically known as Potamotrygon hystrix, is a captivating and unique species that thrives in freshwater environments. Renowned for its distinctive appearance, which includes a speckled pattern across its disc-shaped body and a venomous spine for defense, this stingray is a prized specimen for advanced aquarium enthusiasts seeking a touch of exotic beauty in their aquatic setups.
Origin: Native to the tranquil rivers and floodplains of South America, particularly in countries like Brazil, Argentina, and Paraguay, the Porcupine River Stingray has adapted to a range of freshwater habitats. These environments range from clear waters with sandy bottoms to murky, vegetated areas, showcasing the species' versatility and resilience.
Feeding: In captivity, the Porcupine River Stingray requires a diet rich in variety and nutrition. Preferred foods include meaty offerings such as shrimp, squid, and earthworms, alongside specially formulated pellets for freshwater stingrays. Regular feeding and a balanced diet are crucial for their health and well-being.
Tank Mates: When considering tank mates for the Porcupine River Stingray, it's essential to choose peaceful, bottom-dwelling fish that will not compete for space or food. Species such as larger tetras, peaceful cichlids, and catfish can coexist with the stingray, provided the tank is spacious enough to accommodate everyone comfortably.
Aggression: Generally peaceful towards other fish, the Porcupine River Stingray reserves its venomous spine for self-defense rather than aggression. However, tank mates should be chosen with care to avoid any potential conflicts or stress to the stingray.
Experience Level: Caring for a Freshwater Porcupine River Stingray is best suited for experienced aquarium hobbyists. This is due to their specific care requirements, sensitivity to water quality, and need for a large, meticulously maintained tank.
Water Parameters: Optimal water conditions are critical for the health of the Porcupine River Stingray. The tank water should be soft to moderately hard, with a pH level ranging from 6.0 to 7.5. Temperature should be kept between 75°F to 82°F (24°C to 28°C). Regular water changes and monitoring of water parameters are essential to mimic their natural habitat and ensure their well-being.
In summary, the Freshwater Porcupine River Stingray is a magnificent and intriguing addition to any large, well-maintained aquarium. With proper care, diet, and environment, this exotic species can thrive and become a centerpiece in the aquatic hobbyist's collection.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days.
The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days.
Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
