Yellow Cubicus Boxfish Ostracion Cubicus

Overview: The Yellow Cubicus Boxfish, known scientifically as Ostracion Cubicus, is a captivating marine species that adds both charm and uniqueness to any saltwater aquarium. With its distinct cubic shape and bright yellow coloration, it's a visually striking addition that's sure to draw attention. This species is relatively hardy, but due to its specific care requirements, it's best suited for aquarists with a bit of experience.

Origin: This intriguing species is found in the warm waters of the Indo-Pacific region, ranging from the eastern coasts of Africa, across the Indian Ocean, to the western shores of the Pacific Ocean. They are commonly observed around reefs and lagoons, where they have plenty of hiding spots and food sources.

Feeding: The Yellow Cubicus Boxfish is an omnivore with a preference for a varied diet. In captivity, they thrive on a mix of meaty foods such as shrimp, squid, and marine fishes, along with algae-based foods to ensure a balanced diet. It's important to feed them small, manageable portions multiple times a day to prevent overfeeding.

Tank Mates: When it comes to tank mates, caution is advised. While they are generally peaceful towards other fish, their tank mates should not be overly aggressive or small enough to be considered prey. Suitable companions include larger fish and those that occupy different areas of the tank. It's crucial to avoid housing them with other boxfish or pufferfish to prevent territorial disputes.

Aggression: The Yellow Cubicus Boxfish is generally not aggressive but can be territorial with members of its own kind or similar species. They are known to release a toxin when stressed or if they perish in the aquarium, which can be harmful to tank mates. Proper tank management and monitoring are essential to mitigate these risks.

Experience Level: Due to their specific dietary and environmental needs, as well as the potential risk they pose to tank mates under stress, the Yellow Cubicus Boxfish is recommended for intermediate to advanced aquarists. Knowledge and experience in maintaining water quality and handling potential issues are crucial for the wellbeing of this species.

Water Parameters:
  • Temperature: 72°F to 78°F (22°C to 25.5°C)
  • pH: 8.1 to 8.4
  • Salinity: 1.020-1.025 SG
  • Tank Size: Minimum of 125 gallons (473 liters) to provide ample swimming space and prevent stress.
Regular monitoring and maintenance of water conditions are vital to ensure the health and happiness of the Yellow Cubicus Boxfish. With proper care, this unique and fascinating species can be a rewarding addition to your marine aquarium.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

Super comfortable!!!!
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
They are super soft and large; they come vacuum-sealed and expand very quickly. They aren't heavy, and they are incredible for sleeping and watching TV in bed.
