And I'll round off the selection for now with:
[1] Bermuda Blue Angelfish,
Holacanthus bermudensis[2] Coral Beauty Angelfish,
Centropyge bispinosa[3] Bicolour Angelfish,
Centropyge bicolorCouple of notes to make at this point - in the case of the larger Angelfishes (
Pomacanthus and some of the
Holacanthus species), these undergo a
dramatic colour change from juvenile to adult. If you check out the species in that Genus, and see just how radical the colour changes are, you'll understand why these fishes are popular with the lucky people who can afford to buy and house them. Though in the case of
Holacanthus ciliaris, the Queen Angelfish, that adds to the expense the fact that to grows to be 20 inches long, and as a consequence
needs a 5,000 gallon aquarium if you're going to house it
properly ...
Several of the larger Wrasses also undergo significant colour changes, though some of these are too big for the home aquarium, and are usually only seen in public aquaria as a result.
Then you have the fishes that undergo sex changes. The various Fairy Basslets in the SubFamily Anthiinae are prime examples - these gorgeously coloured fishes begin life as female, and the largest female changes into a male when the resident male in the shoal dies (or is removed via predation). One of the most resplendent of these is the Princess Fairy Basslet,
Pseudanthias smithvanizi, which is one of the true "catwalk stars" of the animal kingdom in terms of colouration.
Meanwhile, a fish that will really leave you with your eyes on stalks when you see it, is the Mandarin Fish,
Synchiropus splendidus, which has pretty much every colour of the rainbow
somewhere on its body. Also featured in the line up of "wow, look at that" fish are
Stonogobiops yasha, the Hi-Fin Clown Goby,
Equetus lanceolatus, the Jack-Knife fish, and
Platax batavianus, the Zebra Batfish (in its
outlandish juvenile form).
One that you sadly won't see in the aquarium, because no one has cracked the secret of keeping it alive in captivity, is
Pseudanthias tuka, the Purple Queen. A photo of this beauty in the wild can be viewed
here.
And now, time to take a break.
