There is no guarantee about
compatibility, but it sounds as
though these fish should be all
right in a tank that size. Be sure
that the snowflake eel has hiding places, and
it should probably be added first. Then add
the harlequin tuskfish. Last, add the Picasso
triggerfish, as he is the inhabitant most likely
to cause problems. Although these are tough
and generally hardy fish, they will seem
quite sensitive as compared to most cichlids.
That is, they will be more disease prone and
more sensitive to water conditions. So make
sure that you maintain good water quality.
A good protein skimmer would be especially
advantageous with these big fish.
and Nano Tanks
I’m looking for small fish
candidates for a nano tank.
Would a fairy wrasse fit the bill in this respect?
perfect for the normal-size mini-reef tank,
they are not good candidates for a nano
tank, as they are active swimmers—and
jumpers—that need a tank that is at least
4 feet long. Another problem is that the
colorful males that are kept by themselves
tend to lose their coloration. The general
opinion is that a lack of females is the
cause of the color loss, as these animals
live in harems of one male and several
females. When females are added to a
tank of a washed-out male, his colors soon
return. Unfortunately, you need a large
tank to keep a harem of flasher wrasses.
I’m not sure about the minimum size, but
I would guess about 75 gallons capacity—
and at least 4 feet long.
I still think that a nano tank is one way for
someone who is interested in mini-reefs to get
started, but you can’t keep fairy wrasses in
them. You might have better luck with one of
the smaller anemonefish such as Amphiprion
ocellaris. Or how about the royal gramma
