Red Stripe Cardinal Ostorhinchus MargaritophorusOverview: The Red Stripe Cardinal, also known as Ostorhinchus margaritophorus, is a captivating marine fish distinguished by its vibrant red stripes that adorn a sleek, silver body. Growing up to 7 cm in length, this species adds a splash of color and elegance to any saltwater aquarium.
Origin: Native to the Western Pacific Ocean, these cardinals are found in reef environments ranging from shallow lagoons to deeper coral slopes, preferring areas with ample hiding spots.
Feeding: Omnivores by nature, the Red Stripe Cardinal thrives on a diet rich in both meaty foods and marine flakes or pellets. Offering a variety of foods, such as brine shrimp, mysis shrimp, and quality commercial foods, ensures balanced nutrition.
Tank Mates: Ideal for a community aquarium, these cardinals are peaceful fish that do well with other non-aggressive species. They are best kept in small groups or pairs to replicate their natural social behavior. Caution is advised with larger predatory fish that may see them as prey.
Aggression: Exhibiting a peaceful temperament, the Red Stripe Cardinal poses little threat to its tank mates. However, they can become territorial with their own kind if the tank is too small or lacks sufficient hiding spaces.
Experience Level: This species is well-suited for aquarists of all levels, including beginners. They are relatively hardy, but maintaining stable water conditions is crucial for their well-being.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed.
I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood).
Overall: high recommend based on my experience so far!
