Let's talk Angelfishes & Butterfly
Fishes
Edited by Elizabeth M. Lukan 3/31/03
Although the two groups are classified separately as Chaetodontidae (Butterfly) and Pomacanthidae (Angels) such is their similarity in appearence and tank habits that it is practical to treat them as one for this post.
The body forms are oval and laterally compressed. These features, along with the terminal mouth, provide a strong clue as to their natural habitat; coral heads, where their thin-sectioned bodies can squeeze easily between the branches. Juvenile Angelfish have a different coloration then their adults and it is not always easy to identify a young Angel with certainty; many species are similar at this stage - blue with white markings.
Of the two groups, Angelfish are the most numerous. The surest way to tell the difference is to look for the spine found on the gill cover of the Angels, but not on the Butterfly.
There appears to be no external differences between the sexes, although at breeding time the females may become noticeably swollen with eggs. Both groups spawn in the same manner, rising in the water to release eggs and sperm.
Most members of the Butterfly family are grazing fishes that feed on algae, sponges and corals; some are omnivorous, however, and include small and planktonic animals in their diets.
Although very attractive, these fishes are not really for the inexperienced hobbyist. They can be difficult to maintain in captivity, particularly the algae and sponge eating ones. The polyp-eating species are almost impossible to sustain. These fish are easily upset by changes in water conditions, usually showing dissatisfaction by going on a hunger strike.
They are fairly territorial and Angels may be intolerant of their own kind, although most of the Butterfly's are compatible. Angels are generally tolerant of dissimilarly-sized fishes; smaller fish do not alarm them, and they do not feel bothered by larger fishes. However, when faced with a fish of the same proportions, quarrelling may occur. In a large tank with a good number of hiding places, you can expect better results. Both Angels and Butterfly's need refuges in which to shelter at night.

Butterfly Fish:
Although I no longer have much interest in buying Angels or Butterfly fish I do have some old timers in my collection (which proves you can keep them alive). At the moment what I have left are:
When I look at the Angel list above I realize I have had all of them except the Queen and Blue-ringed. It all is in how much space you can give them and how peaceful you can keep the tank for them. Fish buying fanatics like me have a hard time setting them up right so better not to buy them for our type set-ups.

Some of the most productive
marine fishing methods are also the most damaging, and should be restricted or
banned, scientists argued at a scientific meeting this week. Today, more than
400 leading scientists called today for the United Nations to issue a moratorium
on longline and gillnet fishing, methods they say are wiping out populations of
fish, turtles, marine mammals and other species in the Pacific Ocean.

New findings about the dynamics
of coastal ocean ecosystems are prompting marine scientists to abandon long held
assumptions about life in the sea and how best to protect it. Working along
coasts from California to the Caribbean, researchers say they have cracked the
"black box" of coastal ecosystems, revealing the inner workings of the near
shore marine environment.

Officials from Delaware and New
