In this section of AC Tropical Fish, you will find
information about all kinds of marine aquariums and the creatures that
inhabit them. In addition to both rare and commonly kept species of
marine aquarium fish you can find information about a long row of other
maritime beings that can be kept in aquaria – perhaps you wish to try
keeping sea anemones, jellyfish or an octopus?
For many fish groups, such as angelfish, blennies,
pufferfish, and seahorses, we have special sections with detailed
articles about popular as well as more unusual species. We also have
sections about stationary creatures like corals, gorgonians, and sea
anemones, as well as sections focused on mobile invertebrates such as
nudibranchs, sea stars, snails, and shrimps. Last but not least, we
have included a section focused on all the different types of equipment
that is utilized by marine aquarists.
If you fail to locate a particular fish species in one of
the article sections, take a look in the tropical marine fish database
instead; it contains brief information on numerous species.
Keeping marine aquariums The tradition of keeping marine creatures in tanks goes
back to at least the Ancient Romans who liked to gather beautiful
anemones form the Mediterranean Sea and place them in jars as
decoration. They did however fail to keep their anemones alive for any
considerable amount of time and the jars had to be constantly refilled
with new anemones from the sea. Today, a devoted aquarist can keep an
anemone alive for many years in the aquarium.
The main reason why so many aquarists decide to spend the extra
time, money and efforts that a saltwater aquarium require is that a
saltwater aquarium can house a wide range of animals that you could
never keep in a freshwater aquarium. It will for instance be possible
for you to keep vibrantly coloured marine fish species like clownfish,
wrasses, anthias and the so called .
A saltwater aquarium can also be filled with live corals, anemones,
sponges, worms and so on. In the saltwater aquariums of advanced
aquarists you can even find jellyfish, octopus and other large
invertebrates.
Is a marine aquarium difficult to maintain? Keeping a marine aquarium is typically more difficult than
keeping a basic freshwater aquarium. There are naturally exceptions to
this rule, some aquarists have freshwater aquariums that contain
species that are extremely hard to keep and breed in captivity. It is
also possible to create a basic saltwater aquarium that beginner
aquarists can handle, as long as you are prepared to gather a lot of
information and develop your knowledge on the subject before you set up
the aquarium. Even advanced freshwater aquarists should read through
the guidelines before they create a saltwater aquarium, since the
ecology of a marine aquarium differs a lot from that of a freshwater
aquarium.
The immense size of the ocean makes rapid changes in
water quality, temperature etcetera unusual and saltwater species are
therefore less resilient to rapid changes. Creating a stable environment
in your saltwater aquarium is therefore one of the key factors behind
successful marine fish keeping. Before setting up a marine aquarium you
should definitely invest in a test-kit that will allow you to keep an
eye on , , ,
and water hardness. A fish species that inhabits a small puddle on the
African savannah is usually very well adapted to withstand rapid
changes, while marine fish species can die if the water temperature or
chemistry of your aquarium alters quickly, even when the change is
comparatively small. Vigorous filtration is therefore necessary, and you
should combine mechanical, chemical and biological filtration. It is
also important to avoid over feeding and uneaten food must be removed
as soon as possible. A saltwater aquarium should ideally be at least
200 litres (55 gallons) since the large water mass will dilute
potentially harmful compounds and keep the environment more stable.
How expensive is a marine aquarium? Generally speaking, a marine aquarium will be more expensive
to set-up than a freshwater aquarium since marine species tend to be
quite pricey and require high-priced equipment to survive, but there
are of course exceptions to this rule. A freshwater aquarium filled
with delicate and high priced species naturally be more costly than a
basic marine aquarium filled with tolerant and fairly inexpensive
marine species. It is possible to set-up and maintain a rather if you go for readily available marine creatures that do not require pristine water quality.
FO, FOWLR or REEF are commonly divided into three broad categories: Fish Only (FO), Fish
Only with Live Rock (FOWLR), and Reef Aquariums. A reef aquarium
resembles a true reef environment and will typically contain various
types of coral as well as other reef invertebrates, e.g. worms, shrimps
and anemones. Many reefs aquarium are actually kept without any fish
at all.
So, what is this mysterious “live rock” used when ?
It is not the rock itself that lives; they name is used for (very
dead) calcium carbonate skeletons or similar calcareous items inhabited
by various marine organism. Exactly which organisms that your live
rock will contain will always come as a surprise since a live rock can
house anything from tiny bacteria and algae to sponges and mobile
invertebrates. Some creatures may not become noticeable until you have
had the rock in your aquarium for several months since they need time
to grow and establish themselves in the tank. Live rock is not only
used to introduce interesting surprise organism to the aquarium; they
main purpose is actually to make the aquarium more similar to the real
ocean by adding organisms that can help build up a tiny ecosystem. Live
rock will help you keep the water quality up and the organisms can
also serve as food for the species you wish to keep. Live sand – sand
inhabited by various oceanic organisms – is also popular in marine
aquariums.
