He's an expert breeder. I think it's funny he was mis-spelling Bangaii

This is the most asked question I receive, and the one question I cannot answer fully. Even though I have seen over 300 banggaiԳ I am only 50/50 on juvenile animals (animals under 1-1.5inches SVL). When the animals reach sexual maturity (12-14 months), then the jawline takes on a characteristic structure, particularly the male which gets squared off. The second dorsal fin is an excellent characteristic, as the males second dorsal extends past the caudal peduncle, however this flowing fin is often nipped off by other fish. The most accurate sexing method: My best method of sexing banggaiճ is using my establish male [the original male banggai from the article]. I introduce another banggai into his tank and within 10 mins he either is trying to kill him (male) or trying to mate with it (female)...HE IS 100% ACCURATE!!! I have sexed many friends banggai this way. Alternatively you can buy 4 or 5 banggais allow then to reach sexual maturity and they will pair off, and please, please, return the unpaired banggais.
