Pseudanthias bimaculatus This is an amazing anthias that is collected in deepwater. This species should be housed in a large aquarium with plenty of swimming room. Acclimation is often slow; your specimen may hide for a week or more before you even catch a glimpse of it. However, in time it will usually come out of hiding, accept live and prepared foods. These fish may behave aggressively toward other zooplankton feeders. Provide clean, well oxygenated water, along with plenty of water movement and open swimming space.
