Fiji Blue Devil Damsel

Chrysiptera taupou

A brilliant electric-blue damsel (the male washed with yellow along the belly and tail) that is almost indestructibly hardy and cheap — but genuinely, intensely aggressive. It defends a rock territory with real ferocity and should be kept one per tank unless a proven pair, and only alongside fish that can defend themselves. Reef- and invert-safe, so it will not touch corals or shrimp, but it is a poor citizen in a peaceful community and is best added last.

Best kept apart

A real clash — aggression, predation or a same-genus fight.

Blue DamselFiji Blue Devil Damsel and Blue Damsel are the same genus (Chrysiptera) and will fight — keep only one.Yellowtail DamselFiji Blue Devil Damsel and Yellowtail Damsel are the same genus (Chrysiptera) and will fight — keep only one.Yasha GobyFiji Blue Devil Damsel (aggressive) is much larger than the peaceful Yasha Goby and may harass it.FirefishThe Fiji blue devil is explicitly "not for docile tank mates"; a shy firefish is a prime harassment target.Yellow Clown GobyFiji Blue Devil Damsel (aggressive) is much larger than the peaceful Yellow Clown Goby and may harass it.Green Clown GobyFiji Blue Devil Damsel (aggressive) is much larger than the peaceful Green Clown Goby and may harass it.Neon GobyFiji Blue Devil Damsel (aggressive) is much larger than the peaceful Neon Goby and may harass it.Azure DamselfishFiji Blue Devil Damsel and Azure Damselfish are the same genus (Chrysiptera) and will fight — keep only one.Talbot's DamselFiji Blue Devil Damsel and Talbot's Damsel are the same genus (Chrysiptera) and will fight — keep only one.Springer's DemoiselleFiji Blue Devil Damsel and Springer's Demoiselle are the same genus (Chrysiptera) and will fight — keep only one.Antennata LionfishAntennata Lionfish has a big enough mouth to eat the much smaller Fiji Blue Devil Damsel.Picasso TriggerfishPicasso Triggerfish has a big enough mouth to eat the much smaller Fiji Blue Devil Damsel.Scissortail DartfishFiji blue devil damsels are intensely aggressive and must not be kept with docile fish; a peaceful dartfish is relentlessly chased and prevented from feeding.Orange Skunk ClownfishAn aggressive blue devil damsel harasses smaller passive fish, including peaceful skunk clowns, and should not share a tank with them.Domino DamselTwo of the most aggressive damsels from different genera (Dascyllus vs Chrysiptera) both defend territory ferociously; housing them together drives constant, escalating fighting.Neon Velvet DamselNeoglyphidodon vs Chrysiptera — both are highly territorial damsels that must be kept with equally tough fish, so pairing them together produces sustained aggression.Zebra DartfishThis damsel defends its territory against any fish that comes near; a timid zebra dartfish is bullied into permanent hiding.Marine BettaMarine Betta has a big enough mouth to eat the much smaller Fiji Blue Devil Damsel.Dragon WrasseDragon Wrasse has a big enough mouth to eat the much smaller Fiji Blue Devil Damsel.Volitans LionfishVolitans Lionfish has a big enough mouth to eat the much smaller Fiji Blue Devil Damsel.
