Lunar wrasse Thalassoma lunare; one way to prevent potential conflicts
when introducing new additions is to remove the most belligerent fish
to temporary quarters when the new fish is introduced.
gallons. You would need something much bigger for its close relative
Diodon hystrix, also known as the porcupine pufferfish. It can reach
a whopping 3 feet in total length and is decidedly not a good candidate
for the home aquarium!
D. holocanthus requires frequent feedings—at least 3 times a day—
and will thrive on chopped meaty marine foods, such as shrimp, clams,
and fish, as well as herbivore formulations. As with many puffers, this
species should occasionally be offered clams and crustaceans still in
the shell to help wear down its teeth. Absent these foods, it becomes
incumbent on the aquarist to file down the fish’s teeth—a practice that
can be stressful to both fish and hobbyist.
Safe to Add Lunar Wrasse?
I would like to buy a lunar wrasse to add to my 180-
gallon fish-only community tank, but first I want to
make sure it will get along with the fish I already have.
My current lineup is one naso tang, one red-tooth trigger, one
queen angelfish, and one zebra moray. Do you see any compatibility
problems with this mix?
The only potential conflict I see with this combination
is between the queen angelfish Holacanthus ciliaris and
the lunar wrasse Thalassoma lunare, as queen angels
are notoriously bellicose, particularly toward newly
introduced tankmates. If the angelfish is still pretty small, you might
not experience any problems, but it will likely be a different story
if you have a larger specimen. As a hedge against aggression, you
could temporarily remove the angelfish to other quarters while the
wrasse gets acclimated to the tank (allowing for a quarantine period,
of course) and rearrange the rockwork to disrupt existing territorial
boundaries. That way, when the angelfish is eventually returned to the
tank, it will no longer be (excuse the pun) queen of the tank and will
be less prone to view the wrasse as an interloper.
Star Polyps Won’t Shine
Over a week ago, I cut back my colony of green star
polyps with sharp scissors to keep it from attaching to
a neighboring rock, which has a leather coral growing Q
