Cosmos Wrasse (Halichoeres cosmetus)
Overview

The Cosmos Wrasse, also known as the Adorned or Elegant Wrasse, is a striking and active reef fish featuring vivid green, orange, and blue markings with a bright yellow tail. Hardy and peaceful, this beautifully patterned species adds constant color and energy to reef or community aquariums while helping control unwanted pests like flatworms and small invertebrates.

Origin

Native to the Indo-Pacific region, including the Maldives, Sri Lanka, and Indonesia, Halichoeres cosmetus inhabits coral reefs and sandy lagoons, often seen foraging among live rock and coral rubble.

Feeding

An omnivore that enjoys a varied diet of frozen mysis, brine shrimp, finely chopped seafood, and quality marine pellets. It also naturally grazes on small invertebrates in the aquarium. Feed 2–3 times daily.

Tank Mates

Peaceful and reef-safe with most species, it coexists well with tangs, gobies, anthias, and other non-aggressive wrasses. Avoid aggressive or overly territorial fish that may intimidate it.

Aggression

Generally peaceful, though minor territorial behavior may occur toward similar wrasses in confined tanks. Provide ample live rock, open swimming space, and a sand bed for resting.

Experience Level

Ideal for beginner to intermediate aquarists. Hardy, colorful, and easy to care for, the Cosmos Wrasse adapts well to mature reef or community aquariums.

Water Parameters
  • Temperature: 75°F – 82°F (24°C – 28°C)
  • Salinity: 1.020 – 1.025 SG
  • pH: 8.1 – 8.4
  • Alkalinity: 8 – 12 dKH

Colorful, hardy, and full of personality, the Cosmos Wrasse is a fantastic addition for aquarists seeking a lively and reef-safe species to brighten their marine aquarium.

Old school denim — not stretchy
Fit Type: Regular, Size: X-Small, Color: Authentic Medium Wash
Fabric used is old school denim — not the thin, stretchy stuff that pretty much everything called “denim” is today. It is 99% cotton (20% of which is recycled cotton) and 1% elastane, but I can’t feel any stretch in the fabric. It is a substantial, non-stretchy denim that gives the jacket really good structure. It has a higher end fit and look than the price would suggest. I wanted a more fitted denim jacket so ordered an XS even though according to the size chart I need a small. (I have a 34.5” bust, 28” waist at 118 pounds 5’4”.) It still buttons over a t shirt or lightweight sweater with freedom for movement/without being tight, but if I wanted a roomy fit or the ability to wear a heavier sweater or sweatshirt underneath and still be able to comfortably button it I would have needed a small. The shoulders are cut broad — I have very broad shoulders and the XS surprisingly fits my shoulders well. This jacket may not be the greatest fit for you if you have very narrow shoulders, unless you are going for an oversized look.

Sexy Comfort Casual Appeal
Size: Medium, Color: Classic Medium Wash
This is a very sexy in a comfortable easy flowing dress. The material feels good on the skin. It is thin and lightweight although long sleeves you will definitely want to wear a jacket or coat with this if you are wearing this in the winter time. It is comfortable and I like the fit on me. I am 5'5 weigh 150 and have large bust size 34DDD I ordered a medium and it fits me well. No gapping at the front where the buttons meet. I think this is a nice Jean dress for the price and the quality is nice. I like it
