Bala Shark question....
Michael Stamper
We have a Bala shark that makes a loud noise sometimes when it is
eating. We can hear him across the room, but it doesn't make the loud
sharp clicking noise all the time. The Bala shark we had before this
one also made this noise when it ate, but it made the sound more
frequently.
I'm curious...does anyone know how they make this sound?
I have ruled out:
1) the food. No other fish in my tank makes this noise when it
eats--besides, the shark eats ONLY soft peas. The first Bala shark made
this noise when it ate shrimp pellets.
2) the interaction with the rocks in the tank. The shark makes the
noise even when it eats peas that are not anywhere near the bottom of
the tank.

their mouth. It could be that they open their mouth fast enough to form a
vacume and then the water snaps in to fill the void. That's my guess
atleast.
I have only ever heard that at the top and bottom of the tank so maybe it
requires the rocks or air to make the sound too.?

and noticed that it only occurs on the bottom and top of the aquarium. For the
top, I figured it was the air inside their mouth that might be causing the
sound. Or even muscles contracting forcing the air out quickly which causes
the sound. And the sound only seems to occur on the bottom when they are
eating pellets and the gravel moves around.
But I have never heard any other type of fish make the sound so I figure it is
quite unique to the bala shark.
Just my two cents.

I have a columbian shark which makes a clicking sound, not when it's
eating though, usually when it's swimming about. We thought it was a form
of sonic navigation. They get really active sometimes.
I've been reading up on them and apparently adults live in brackish water
and are migratory, like salmon, so maybe it's calling for it's friends.
Unfortunately I now feel that these sharks should not be kept in
captivity. Because of the migratory instinct it can only be cruel and I
can't provide brackish water conditions or a large enough tank. The bala
or silver sharks are a much better bet.
The columbian shark is now sick - it has opaque glazed eyes and white
marks (not fungus or white spot) and is very listless. Does anyone
recommend a treatment for this? Or would euthanasia be the right thing
considering it's future?
