Blood Spot Anthias – LiveAquaria
The Blood Spot Anthias, also known as the Yellow Lined Anthias, makes a beautiful addition to the fish-only, invertebrate, or reef aquarium. Males have three yellow lines and a red spot on their dorsal fin. The red head fades to a vibrant yellow extending to the tail.
The Blood Spot Anthias does best when kept with its own species in a tank of at least 125 gallons. In their natural habitat, Yellow-Lined Anthias inhabit steep reef faces and drop-off areas. In the home aquarium, the Anthias typically 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.

The Blood Spot Anthias adds a striking visual presence to my 150-gallon reef tank. The coloration is vivid, especially the yellow tail and red dorsal spot. I keep them in a group of five, and they seem to be very active and peaceful. They enjoy the rock structure and hide in crevices during the day. The hermaphroditic trait is fascinating to observe when one of the males dies and a female takes over.

I’ve had these fish for six months now. They are very social and need plenty of space and hiding spots. The yellow lines and red spot on the male are very noticeable. I’m happy with the color and behavior, though they do require a large tank and stable water conditions.

The Blood Spot Anthias is a stunning addition to my aquarium. The color change from red to yellow on the head is beautiful. I keep them in a group and they seem to get along well. The tank setup with live rock provides enough cover, and they are active but not aggressive.
