🐠 Dispar Anthias (Pseudanthias dispar)
Marine Reef-Safe Shoaling Fish • Vivid Red-Orange & Yellow Display Fish • Active Open-Water Swimmer • Beginner-Friendly Once Settled
 
📋 The Dispar Anthias (Pseudanthias dispar), also known as the Redfin, Peach, or Madder Seaperch Anthias, shows striking sexual dimorphism — males display a vivid orange-red body with a bright red dorsal fin, while females are yellowish-orange on top fading to a pale lavender-white underside.
Native to shallow, current-swept reef faces and drop-offs across the Indo-Pacific, from Christmas Island to the Line Islands, south to the Great Barrier Reef and Fiji, this species naturally shoals in large numbers, constantly swimming through the water column in search of zooplankton.
One honest note worth knowing: the first month after introduction is genuinely the trickiest period for this species — it can be shy and takes some time to settle, but becomes noticeably hardier and more confident once established. It's best kept as a mated pair, a small group of females, or a proper harem of one male with several females in odd numbers; avoid keeping two males together, as this leads to real aggression.
With a spacious tank, ample food, and patience during the settling-in period, it thrives as a Vivid Active Shoaling Reef Display Fish.
