The Bartlett's Anthias is also known as the Bartletts Fairy Bass. The males have a more intense coloration with a violet body and yellow running along the back through the upper caudal lobe. The females tend to be lavender in color with a yellow back and caudal fin.

The Bartlett's Anthias does best when kept with its own species in a tank of at least 70 gallons, but is also a beautiful fish for the fish only, invertebrate, or reef aquarium. The Anthias dwells in the middle of a tank but appreciates the availability of several hiding places.

Anthias species all share the trait of being hermaphroditic. If a dominant male perishes, the largest female of the group will often morph to take its place.

Once acclimated to a new aquarium, Anthias do best when fed a varied diet of frozen mysis shrimp, enriched frozen brine shrimp, and over time may eat high-quality flake foods offered in small quantities throughout the day. An attached refugium cultivating copepods and amphipods provides a steady supply of nutritious live food sure to keep this active planktivore content.

At this time we are unable to offer Bartlett Anthias by specific gender, and unfortunately cannot guarantee specific quantities of males or females. This species is purchased from the supplier overseas in quantities and not by gender, so we have available for sale what is currently harvested. Enthusiasts who wish to purchase a male and several females, please visit the Diver's Den section for harems of these fish as well as other Anthias species.

Approximate Purchase Size: Small 1" to 1-1/2", Medium 1-1/2" to 2", Large 2" to 3"

Customer Testimonials

Jason H Mobile , AL
Great little fish. She was very shy when I first introduced her. After a few weeks though, she is all over the tank. Very glad I picked this one up from DFS.
Rusty W Bossier , LA
I recently bought a male and 2 females from Diver's Den. They were very alert and healthy when I recieved them. The male I got looks awesome, mostly a vibrant pink with streamers on the tail. DFS does such a great job at shipping fish. They use seven bags, one being black, to ship each fish! Don't buy from anyone else! Thank You DFS.
Double A Seattle , WA
I received two trios from the Diver's Den and all I have to say is WOW! Fantastic looking fish. According to LA's feeding chart, they were feeding frozen food mostly. All anthias were eating NLS pellets on the first day with gusto! These guys were jumping all over the place during acclimation, so make sure you cover up your buckets when they arrive. It goes without saying that you should have some sort of covering on your tank as well. Beautiful fish - they were not shy at all. All looked curious when i walked by the tank. They also followed me around on day two, showing recognition that I was feeding them. LA and the Diver's Den definitely had these guys acclimated to captivity. If you have the room, stock these anthias, they make a great display fish all on their own!
