Red Tail Bicolor Blenny Escenius BicolorOverview: The Red Tail Bicolor Blenny, a vibrant addition to any marine aquarium, is known for its unique coloring and peaceful demeanor. With a striking combination of blue in the front half of its body and a vivid red-orange tail, this species is a visual delight. Reaching up to 4 inches in length, they are perfect for small to medium-sized tanks.
Origin: Native to the Indo-Pacific region, these blennies thrive in coral-rich areas and rocky crevices, often found at depths between 2 to 25 meters. Their natural habitat is characterized by warm, clear waters.
Feeding: Omnivorous by nature, their diet should include a variety of marine algae, vegetable matter, and occasional meaty foods. High-quality marine flake foods, spirulina, and frozen preparations will keep them healthy and vibrant. It's important to feed them small amounts two to three times a day.
Tank Mates: Bicolor Blennies are generally peaceful and can coexist with a wide variety of tank mates. Ideal companions include smaller, non-aggressive fish species and invertebrates. However, they should not be housed with large, predatory fish or other blennies that might compete for territory.
Aggression: While mostly peaceful, they can become territorial towards other blennies and similarly shaped fish, especially in smaller tanks. Providing plenty of hiding spots and live rock for grazing can help minimize aggression.
Experience Level: Suitable for both beginners and experienced aquarists, the Bicolor Blenny is relatively hardy but requires a stable, well-maintained tank to thrive. Regular water changes and monitoring are essential.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.

Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.
HRV, readiness & total sleep score metrics increased drastically this week. See screenshot :)
Support:
Molds and cushions every crevice under my neck and above shoulders. So comfy
Size:
Adjustable loft but king length is perfect to hug and rest your head. Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated.. my Oura ring showed both nights I was awake every hour. Not good. Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep. Huge.
Weight:
Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders
Softness:
Like the baby bear.. just right.
Comfort:
Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.
If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back.
I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size.
pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking
cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King.
I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem.
A shame, would have given them a great review if they were the correct size
