Black Widow Combtooth Sailfin Blenny Altosalarius FasciatusOverview: The Black Widow Combtooth Sailfin Blenny is a unique and captivating species, cherished by aquarists for its vibrant personality and striking appearance. With its distinctive black body contrasted by vivid, iridescent lines and a remarkable sail-like dorsal fin, this Blenny is a showstopper in any marine aquarium.
Origin: Native to the coral reefs of the Indo-Pacific region, the Black Widow Combtooth Sailfin Blenny thrives in environments rich in coral and rocky crevices. They are adept at blending into their surroundings, making them both intriguing and challenging to spot.
Feeding: Omnivorous by nature, their diet should include a variety of foods to maintain optimal health and coloration. Offer a mix of marine algae, spirulina, and high-quality prepared foods. They also appreciate live and frozen foods such as brine shrimp and mysis shrimp, providing essential nutrients.
Tank Mates: Ideal for a community aquarium with peaceful to semi-aggressive fish. Compatible with most reef inhabitants, avoid housing with large predatory fish or those known to nip at fins. Tank mates should be chosen carefully to ensure harmony within the aquarium.
Aggression: Generally peaceful, though they can exhibit territorial behavior towards their own kind or similar species. It's advisable to keep only one per tank unless the aquarium is large enough to provide ample space for each individual.
Experience Level: Suitable for aquarists of all levels, from beginner to expert. Their hardy nature and adaptability make them a rewarding choice for those new to marine aquariums, while their unique behavior and appearance appeal to experienced hobbyists.

Get one but use it on a medium firm mattress, not a firm one.
Number of Items: 1
You need a mattress that is medium firmness to use this wonderful pillow. It gives perfect neck support and I can sleep on all 4 sides with it. My neck/head pain quit first night used it. On a firm mattress it feels too hard and awkwardly cradle l es my head.

Great Pillows
Number of Items: 2
Got the 2pk, while these are probably not worth $65/pillow, they are definitely comfortable and I had no issues sleeping on it. Much better than the memory foam pillows from Walmart.
Could be a bit bigger and denser on the foam, but otherwise its perfect.
Pair with nylon cover for better cooling.

Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!
