I should point out that there are various
Acestrorhynchus species that reach a much
more manageable adult size. For example, A.
altus and A. britskii only get about 6 inches long
and A. isalineae usually reaches only about 3 to
Occasional feedings of snails will help pufferfish such as the dwarf puffer Carinotetraodon
travancoricus keep their teeth properly worn down.
I’m thinking of buying four
dwarf puffers Carinotetraodon
travancoricus to put in a 20-gallon species
aquarium. In doing some research, I found
that they need to be fed snails along with
their normal diet to prevent their teeth
from overgrowing. With school and other
daily activities in the way, I’m not sure
if routine trips to a store to get snails for
them would be an option for me. Is there
a substitute I can use instead?
Hello TFH I am a 13-year-
old hobbyist, and I really love
tropical fish. One fish I really like is the
cachorro barracuda. I know it’s not really
a barracuda and that it eats fish, but that’s
about all I know. How big does it get? Is it
possible to keep a male/female pair? I’d also
like to know how big of a tank it would
need and what tankmates it could have.
Any help will be appreciated.
In my opinion, snails are
really your best option for
keeping dwarf puffers’ teeth
from overgrowing—not to
mention they are a major part of their
natural diet—but it really shouldn’t be
necessary to make repeated trips to a
store to get them. Before you set up your
dwarf puffer tank, I would recommend
setting up a small tank for the purpose of
culturing snails (such as ramshorn snails)
that can be fed occasionally to the puffers.
I’ve seen the common name
“cachorro barracuda” applied
to several species of barracuda-like fish belonging to the genus
Acestrorhynchus. You’re absolutely right
that these fishes aren’t true barracudas.
In fact, they’re actually characins, more
closely related to tetras. How big they get
varies by species, but the two species most
commonly sold under this common name (at
least from what I’ve seen), A. falcatus and A.
falcirostris, can grow to about 12 inches and
15 inches respectively.
It shouldn’t be hard to source a handful of
snails to get the culture started, since most
hobbyists and dealers who have them in
their tanks are more than happy to part
The snail culture tank wouldn’t have to
be anything fancy or expensive. A bare-bottom 5- to 10-gallon tank equipped with
a small sponge or hang-on filter and a
heater will work just fine. Lighting is not
crucial, but it can be helpful because it will
promote the growth of algae. The snails can
be fed terrestrial greens (lettuce, zucchini,
etc.) along with various sinking fish foods
in pellet or wafer form.
In general, Acestrorhynchus species are
best kept in groups of at least three, so trying
to keep a male/female pair probably isn’t
your best bet. Besides, it’s pretty hard to tell
the males from the females. Because of their
large adult size and the fact they should be
kept in groups, a very large aquarium is
necessary to house these fish. I wouldn’t go
with anything smaller than a 125-gallon tank
for a group of three.
