FAQ

Are male Watanabe Angelfish reef safe?
Yes. Watanabe Angelfish are generally considered reef compatible and are much less likely to bother corals than many other angelfish. As with any livestock, individual behaviour can vary.

How big does a male Watanabe Angelfish get?
Adults can reach approximately 15 cm. They are active swimmers and benefit from plenty of open swimming space.

Can a male Watanabe Angelfish be kept with females?
Yes. A male can be kept with one or more females in a sufficiently large aquarium. Watanabe Angelfish are protogynous hermaphrodites, meaning females can change sex and develop into males.

Offer a varied diet of frozen mysis, finely chopped seafood, quality marine pellets and other suitable meaty foods. Several smaller feedings throughout the day are beneficial.
