These are solitary, active fish which quickly go into hiding when they are disturbed. They must cohabit
with species of the same size, in a decor furnished with hiding places.
Pseudochromis diadema
This resembles the royal gramma, with which it can cohabit -
which is not the case with members of its own species. It flaunts a
golden yellow coloring set off by purple. It feeds on small, live prey
and pieces of mussel. This fish is recommended for invertebrate
aquariums with enough space for it to hide. Size: 7 cm
Half-black angelfish
Centropyge vroliki
This is one of the largest fish in this genus:
the half-black angelfish acclimatizes well
and flourishes in captivity, accepting both
live and dead prey. It is particularly
aggressive towards other dwarf angelfish
when it is deprived of sufficient space.
Size: 13 cm

Lemonpeel angelfish
Centropyge flavissimus
The eye of the lemonpeel angelfish is framed by a blue circle;
the juvenile has an ocellus (eyelike spot) in the middle of each side.
It accepts small items of food, but keeping it in captivity has its
complications. This species is fragile and is rarely imported.

Potter's angelfish
Centropyge potteri
The Potter's angelfish is placid and accepts a wide range of
food. Nevertheless, it is sometimes considered delicate for an
aquarium. Size: 10 cm

Yellow angelfish
Centropyge heraldi
The yellow angelfish resembles the lemonpeel
angel, although it does not have the blue marks on
the eye, operculum, and fins. This delicate species is
rarely imported. Size: 10 cm.

Flame angelfish
Centropyge loriculus
One of the most beautiful dwarf angels, the flame angelfish
appreciates hiding places in an aquarium. It feeds on algae and
brine shrimps, but may also accept commercial food. Size: 7 cm.

Flame back angelfish
Centropyge acanthops
This is a small species, relatively
easy to keep, but rarely found
in the aquarium trade. The
flame back
angelfish likes
hideaways and
feeds on algae
and small
invertebrates. In
some specimens,
the eye is
surrounded by
a blue circle.

Eibl's angelfish
Centropyge eibli
Eibl's angelfish, aggressive towards all
the other species in the genus, is easy to
keep in captivity. Its vegetable diet can be
complemented by small invertebrates.
Size: 12 cm.

Bicolor angel
Centropyge bicolor
In nature, the peaceful
bicolor angel live in groups,
but this is not possible in
captivity, except in very large
aquariums. It is sometimes
difficult to keep in a tank and
has a reputation for being a
fussy eater. Its basic diet
consists of brine shrimps,
tubifex worms, and chopped
mussels. Size: 10 cm.

Rusty angel
Centropyge ferrugatus
The medium-sized rusty angel can be confused
with other species. However, it is recognizable
from the fine blue stripes on the dorsal and
anal fins. The caudal fin is not convex.

BALISTIDAE (TRIGGERS)
Triggers live in reef areas where the water is in constant movement, so you must plan a large aquarium
for them (at least 400 liters) with highly agitated and well-oxygenated water. Their jaws and teeth
allow them to graze on coral, crabs, and mollusks. In captivity they accept animal food, such as small mollusks (cockles, mussels), complete with their shells. They are fairly aggressive and must be kept singly, away from small fish and invertebrates. One of the distinguishing features of this family of marine fish is its ability to stick out the first spoke of its dorsal fin, and then block it with the second one (explaining their alternative name of crossbowmen).

Dwarf Lionfish
The dwarf lionfish does not grow longer than 15 cm, in contrast
to the Pterois. It is also distinguished by the absence of a
membrane between the spokes of the pectoral fins.

membrane between the spokes of the pectoral fins.
Size: 15 cm.
Volitan Lionfish
Pterois volitans: The volitan lionfish is the one most often
found in the aquarium trade. It gets
accustomed to dead foodstuffs. The
membrane linking the spokes of the
pectoral fins runs to the rear end of their
body, which is not the case with the other
species of the Pterois genus, where the
rear is unencumbered.
Size: 35 cm
SCORPAENIDAE (LIONFISH)
Lionfish are not only stunning to look at, but they can also
constitute a real danger for an aquarist: some of their spiny
spokes emit a venom similar to that of certain snakes. They are placid
and majestic fish, easy to keep in an aquarium of at least 300 liters.
The tank must be furnished with elaborate and convoluted decor,
complete with grottoes and overhangs: lionfish swim through them
flat or at an angle. Their large mouth is equal to their voracity: they devour live prey, often small fish (take care with their roommates!). Nevertheless, these remain amongst the most deirable subjects for the amateur aquarist and repay without any doubt any amount of trouble.

Dwarf angelfish or Centropyges
These also belong to the Pomachantid family and share its characteristic spine. They are mainly native to
the Indo-Pacific region, where they frequent the coral reefs taking shelter in caves or under overhangs.
Territorial; they can be aggressive with members of their own species, or with Centropyges with a similar
coloring. They are sociable with other fish and respect invertebrates. They are rarely longer than 12 cm
and require an aquarium of at least 200 liters, equipped with places to hide. Their natural diet mainly
consists of algae; in captivity, a vegetable diet of spinach and lettuce can be topped off with small, live
prey, especially crustaceans.

Longnose butterfly
Forcipiger flavissimus
This is an easy species to acclimatize if it has
not suffered too much during its importation.
Not inclined to be aggressive (except against
members of its own species), the longnose
butterfly likes to have some hiding places. Its
diet comprises mussels, tubifex worms, or fish
flesh. Size: 15 cm.

Banded butterfly fish
Chaetodon striatus
The banded butterfly fish, like the C. capistratus and the C
ocellatus, is native to the tropical Atlantic, while the other
butterflies come from the Indo-Pacific region. It does not pose any
problems once it has become used to small food items
(crustaceans and anemones of the Aiptasia genus). Size: 15 cm.

BUTTERFLY FISH COLORING
The coloring of adults is often slightly different from that
of juveniles (size less than 5 cm), the black patch on the
rear of the dorsal fin sometimes disappearing in adults.
It seems to act as a false eye (the real one being surrounded
- and hidden - by a band or black patch) to
deceive an enemy and surprise it by fleeing "in reverse."
However, this theory has yet to be proven. Once the fish
are fully grown, the juvenile bands can fade or disappear
completely, although some, in contrast, can get bigger.

Masked butterfly fish
Chaetodon semilarvatus
The highly active masked butterfly fish searches out
small prey near the substrate or in the algae, but it also
swims in open water. Its
maintenance can pose
problems, as it is
sometimes considered
to be delicate.
Size: 20 cm.
