The care required for an invertebrate only tank is
very similar to that of any other saltwater tank; however, the invertebrates are
far less hardy than fish. It is recommended that you become skilled with a fish
only tank before attempting an Invertebrate aquarium. Most Invertebrates require
a specialized diet. Check with the supplier before purchasing and be sure that
you are willing to make the commitment to have food delivered if necessary.
There are two different types of invertebrates, tropical and cold water. Make
sure that the type you are buy is compatible with its other tank mates.
A few examples of tropical invertebrates are tubeworms, red hermit crabs,
cleaner shrimp and the sea apple. All of this marine life is compatible in terms
of water conditions. They require a water temperature between seventy five and
seventy nine degrees Fahrenheit, a P.H. between 8.2 and 8.4 and a salinity
content of 1.020-1.024. As you can see, there is very little wiggle room
associated with these measurements. It is extremely important to check the
levels daily, or the results could be costly. These invertebrates are not
compatible, however, with their food source needs. Check with the supplier for
compatibility before combining tropical invertebrates.
Unlike their tropical counter parts, cold water invertebrates are usually not
sold in stores. They have to be collected from tide pools. It is important to
make sure that these species are not on the endangered species list before
removing them from their home. It is equally important to do research in order
to verify that you are able to properly feed them and care for their very
specific needs. Sea Anemones, prawns, shrimp, and starfishes are a few varieties
that have been successfully maintained in an aquarium. They require a water
temperature between fifty four and fifty nine degrees Fahrenheit, a P.H. between
8-8.4 and a salinity content of 1.024-1.025. Luckily they do eat the same food.
They feed off of a diet of small pieces of raw fish, shrimp, squid and mussels.

When keeping cold water invertebrates such as the
species mention above, it is a good idea to keep a separate tank full of shrimp,
mussels, and scallops to be used as a food source, if you wish to use fresh
rather than frozen foods. Be careful when keeping shrimp, as all of the
invertebrates listed above feed on shrimp, including shrimp themselves. It is
unlikely, however that a healthy live shrimp will be eaten whole by another
shrimp or starfish. Invertebrates should be fed more frequently in smaller
amounts than fish. Try to feed only an amount that can be consumed in the first
thirty to sixty seconds.
When setting up an invertebrate tank remember to include live rock, because some
invertebrates feed on the parasites that grow on the live rock. A substrate
should also be included in this type of aquarium. It will provide a place for
the crabs and shrimp to dig and bury themselves. A light should be included as
well, if you intend to keep anemones.
