The butterflyfish are a group of conspicuous tropical marine fish of the family Chaetodontidae; the bannerfish and coralfish are also included in this group. The approximately 129 species in 12 genera are found mostly on the reefs of the Atlantic, Indian, and Pacific Oceans. A number of species pairs occur in the Indian and Pacific Oceans, members of the huge genus Chaetodon. Butterflyfish look like smaller versions of angelfish (Pomacanthidae), but unlike these, lack preopercle spines at the gill covers. Some members of the genus Heniochus resemble the Moorish idol (Zanclus cornutus) of the monotypic Zanclidae. Among the paraphyletic Perciformes, the former are probably not too distantly related to butterflyfish, whereas the Zanclidae seem far less close. Butterflyfish mostly range from 12 to 22 cm in length. The largest species, the lined butterflyfish and the saddle butterflyfish, C. ephippium, grow to 30 cm. The common name references the brightly coloured and strikingly patterned bodies of many species, bearing shades of black, white, blue, red, orange, and yellow. Other species are dull in colour. Many have eyespots on their flanks and dark bands across their eyes, not unlike the patterns seen on butterfly wings. Their deep, laterally narrow bodies are easily noticed through the profusion of reef life. The conspicuous coloration of butterflyfish may be intended for interspecies communication. Butterflyfish have uninterrupted dorsal fins with tail fins that may be rounded or truncated, but are never forked. 31215

Ídolo Moro
Uno de los peces más difíciles de mantener en un acuario de casa (y muy caros también), para la mayoría de los acuaristas ídolo moro son el pináculo de la afición. Algunos pueden pensar que lo han visto antes, pero estás son probablemente confundidas con otras especies, el Bannerfish (también conocido como el ídolo falso). Con el distintivo de disco comprimida y cuerpos similares, ídolos morisco en bandas de contraste negro, blanco y amarillo, que los hacen parecer muy atractivo para los poseedores del acuario.
El ídolo moro (Zanclus cornutus), única especie del género Zanclus, que a su vez es el único encuadrado en la familia Zanclidae. Es un pez marino del orden Perciformes, distribuido por aguas tropicales y subtropicales de los océanos Índico y Pacífico.
Aparece por primera vez en el registro fósil durante el Eoceno medio, en el Terciario inferior.
Tiene el cuerpo en forma de disco, muy comprimido lateralmente, mandíbula tubular con una pequeña boca conteniendo numerosos dientes largos. Lo más característico de su morfología es que las espinas de la aleta dorsal están alargadas en un filamento similar a un látigo.3 Delante de los ojos tiene unas protuberancias córneas, que dieron el nombre latino a la especie: cornutus, o cornudo.
La coloración base de cabeza y cuerpo es blanca, con 3 franjas verticales negras, la primera y más ancha va desde el nacimiento de la aleta dorsal hasta las aletas pélvicas, la segunda nace en la parte posterior de la dorsal y cubre la parte posterior de la aleta anal, y la tercera cubre la aleta caudal. Tiene una mancha amarilla horizontal en el nacimiento del hocico, y otra, también amarilla, recubre la mayor parte del cuerpo.
Esta especie es muy similar en apariencia a las especies Heniochus acuminatus y Heniochus diphreutes, provocando frecuentes errores de identificación. Las diferencias más fácilmente apreciables son: la ausencia de la mancha amarilla de la parte posterior del cuerpo del Ídolo moro en las especies del género Heniochus; el hocico más estrecho y largo del Z. cornutus, que además tiene una mancha amarilla, bordeada en negro, en su unión con la cabeza, que los Heniochus no tienen; o que los ojos del Ídolo moro están cubiertos por la franja vertical negra, y en los Heniochus no, siendo claramente visibles.
Heniochus Diphreutes - The skeleton of this schooling banner fish has been coloured with dyes that stain the bones red and the cartilage blue. The flesh has been rendered transparent.
tropical fish at the Riverhead Aquarium...
The schooling bannerfish, also known as the false moorish idol, is a marine ray-finned fish, a butterflyfish from the family Chaetodontidae. It is native to the Indo-Pacific area.
Another fairly unusual underwater photo.
People with aquariums worry if their fish swim upside down but it seems to be natural for some fish to do this in certain situations. Here a juvenile Masked bannerfish, Heniochus monoceros ( the black yellow and white one) is swimming upside down in the company of some Crown squirrelfish, Sargocentron diadema ( red and white stripes and bad tempered looking ) and a band of young Striped eel catfish Plotosus lineatus ( strped white and dark grey ones at the back).
Masked bannerfish can also swim the right way up and usually do so when swimming in the open. Another fish that also swims upside down is the forceps butterfly fish ... so far I don't have as good a photo of one doing it.
Swimming upside down under a rock or coral presumably makes it harder for a predator to catch you - it certainly made it more difficult to get the photo.
