a well-aerated or filtered tank a must for the
successful shrimp keeper. Moreover, these
animals like low light and many hideaways
where they can stay during the day.
Like all crustaceans, shrimp have to shed
the old exoskeleton they have outgrown
at regular intervals and form a new one.
The old exoskeleton breaks open between
cephalothorax and abdomen, and the shrimp
frees itself by jerky, sudden movements. This
process is also called molting.
After the molt, the shrimp’s body is still
very soft, which makes the animal highly
vulnerable. Shrimp will usually hide from
possible predators after shedding their old
exoskeleton to avoid being disturbed while
the new one hardens.
Shrimp Tank Setup
Most shrimp that can be kept in an
aquarium are good swimmers. Unlike
fish, however, they don’t need open water
to swim, but rather prefer a really well-structured tank that provides various
surfaces to sit on. For this purpose, you
can use all kinds of aquarium decorations.
Dwarf shrimp will even perch on the
vertical glass panes of your aquarium if a
little algae and biofilm have had the chance
to form on them.
Fan shrimp need a sufficient number of
places to sit, depending on the size of their
group, where they can make full use of the
current and still find some shelter. If there
are not enough of such places in the tank,
they may start fighting for a good place.
Long-arm shrimp need a well-structured
aquarium, especially if you are planning
on keeping more than one (which is not
possible for all long-arm shrimp species) or
breeding them. As these larger shrimp are
not really great swimmers, especially when
they grow bigger, it is important to provide
them with three-dimensional structures in
the tank where they can climb. They also
like caves and hideaways under wood and
rocks where they can retreat.
Depending on the type of shrimp, their
requirements regarding filtration differ
considerably, too. Tanks dedicated to
dwarf shrimp can be equipped with small
internal filters, air-driven sponge filters, or
undergravel filters, for example. A slight
flow is preferable.
Even though many dwarf shrimp species
originate from small creeks, it is not
necessary to provide them with a strong
current, and, in fact, a strong filter brings
A “berried” (or egg-carrying) blue tiger shrimp will typically carry her eggs for two to three
weeks, depending on water temperature.
Although many shrimp originate from bodies of water with little vascular plant life, they seem to
thrive in densely planted tanks.
