FAQ
Are Lyretail Anthias reef-safe?
Yes, Lyretail Anthias are completely reef-safe. They will not bother corals, clams, or other invertebrates.
How often should I feed Lyretail Anthias?
Anthias have a fast metabolism and do best with 2–3 small feedings per day rather than one large feeding. A refugium that produces copepods can help supplement their diet between feedings.
Can female Lyretail Anthias change sex?
Yes. All anthias are protogynous hermaphrodites — meaning they are born female. If the dominant male is removed from the group, the largest female will typically transform into a male over several weeks.
How many Lyretail Anthias should I keep together?
They do best in groups of 5 or more with only one male. A single female can also be kept, but they are much more active and confident in a group setting.
