overview
The Bimaculatus Anthias is also known as the Twospot or Twinspot Anthias. The males have one or two spots on their dorsal fin, with a pink head that fades to a vibrant red extending to the tail. Irregular pink bars run horizontally along the body, making this fish one of the most gorgeous of all Anthias. The females of the species are pink with a yellow dorsal, anal and caudal fin. These unique Anthias are beautiful fish for the fish only, invertebrate, or reef aquarium.
The Bimaculatus Anthias does best when kept with its own species in a tank of at least 70 gallons. A marine species, 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.

The diet is consistent with other members of the Anthias group - zooplankton and floating filamentous algae. In the aquarium, it should be fed a varied diet of mysis shrimp, vitamin-enriched brine shrimp, frozen preparations and other meaty items for zooplankton feeders, and small quantities of food several times per day.

Approximate Purchase Size: Small: 2" to 3" Medium: 3" to 4" Large: 4" to 5"

 

When the people selling these fish give tank size requirements it is due to the fishes needs.It would be to the benefit of anyone selling fish to have the most potential customers i.e. smaller min. tank sizes would equal more potential buyers.These tank size requirements are there for a reason.That reason depends on the species and its habits.You will also notice these tank size requirements don't say 70 gallon for an adult but 20 gallon for a juvenile.There are reasons for that as well not the least of which is trying to catch a fish once added to a fully stocked tank is next to impossible(most of the time) without removing all the rocks.It is always best to use caution and keeping a fish listed for a 70 gallon aquarium in a 20 gallon tank is the opposite IMO.You can't ask the fish if it's happy and unfortunately WC's are not going to make the tank bigger.

overview
The Resplendent Anthias is also known as the Tierra Anthias or the Resplendent Goldie. One of the more common color variations is predominantly yellow highlighted with red on the anal and caudal fins. The body of the female is predominantly orange with a pink/purple hue and a yellow nose, dorsal fin and tail fin. Males are predominantly orange with the same pink/purple hue but have an almost clear tail and deep pink edges on their pectoral fins.
Resplendent Anthias generally stay in the middle levels of the tank, but also require plenty of caves, ledges, and other hiding places. Although a 25-gallon tank will suffice for one fish, if keeping a group of one male and several females, a 125-gallon tank or larger tank is needed.

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.

This Anthias does best when fed twice a day and does well on a diet of seafood, frozen, and flake foods with lots of variety.

Approximate Purchase Size: Male: 1-1/4" to 2-3/4" Female: Small 1 1/4" to 1 3/4" Medium 1 3/4" to 2 1/2"

The fish has only been in the tank for a few months so saying it is just fine doesnt hold much ground. I'd try and get it out if possible.

 

Um, the little 20g. is coming up just a wee bit short of what these fish need, even if a person is only housing one.
