(HYDRA VIRIDISSIMA)
Hydra are the freshwater relatives of
jellyfish, sea anemones, and corals.
There are many different species of hydra
and they occur on every continent except
Antarctica. Some are clear, white, brown,
or even green like the ones you see here.
Large numbers of hydra are commonly seen
in fry grow-out tanks where we've been feeding
the newborn fish with lots of small live foods
such as the baby brine shrimp that you see here.
Hydra have two ways in which they can reproduce.
They can do it asexually through a process known as
budding where a new hydra begins to grow from
the body of the parent.
This method of reproduction produces an exact
clone of the parent, and it's the main method
that the hydra uses to create new individuals.
The budding process can produce a new hydra
in just a few days. And once the process is
complete the newly formed hydra will detach
from its parent and float away to a new location.
Nonetheless, a hydra can either be a male,
a female, or a hermaphrodite. If it's a male
hydra it will develop testes that produce sperm.
And if it's a female hydra it will
have an ovary that produces eggs.

Because not only can they reproduce by budding,
and by producing resting eggs, but any small piece of
the hydra can grow into a whole new individual.
And this is because hydra have specialized
stem cells that can change into any type
of cell that they need, which allows the hydra
to regrow any body part that they want.
Furthermore, hydra are constantly regenerating every cell
in the body so that they never really get old and
they're practically immortal.
However, they can die of disease, starvation,
or by being poisoned, as well as by being eaten,
but other than that, they can theoretically live forever.
In fact, you can even take a hydra and blend it up
into a liquid and the individual cells can then
reassemble themselves back into a whole new hydra.
The species of hydra that we've been looking at
throughout this video is called Hydra viridissima,
and it gets its green coloration from a very
specific type of single celled algae that lives
and grows inside the hydra.
The algae and the hydra have what's known
as a symbiotic relationship where both species
can benefit from each others presence. And the
basis for this close relationship is an exchange of
nutrients between the two species.

So, over-feeding of prepared foods can
inadvertently cause an outbreak of hydra.
So, the question now becomes, how do we get
rid of the hydra because many people worry that
the hydra are going to eat their baby fish
as well as their newborn shrimp.

A HYDRA OUTBREAK
There are two chemical treatments that are often
recommended. One is called "No Planaria" and
the other is a chemical called Fenbendazole that
is used to get rid of worms in goats.
Both of these chemicals will also kill snails,
and if used incorrectly might also harm your
shrimp as well. So, always follow the manufacturer's
instructions and monitor your fish and shrimp
for any signs of distress.
Some other options for dealing with hydra
are to use fish that might eat them such
as paradise fish, honey gouramis, and sparkling
gouramis, but these fish need to be hungry in
order to go after the hydra, and they might also
eat your shrimp.
