If
you wish to keep a live aquarium, or you already have
a live aquarium, our mission is to help you make sound
choices when investing in aquarium supplies and inhabitants.
The term live aquarium (as opposed to dead aquarium)
is a term used to describe it actual aquarium as opposed
to aquarium screensavers commonly used on computers.
Years ago, before computers, there was no need to use
the term live aquarium. This web site also uses the
term live aquariums to describe fish tanks about inhabit
invertebrates, plants, and fishes. Live aquariums usually
refer to saltwater tanks.
The
entire animal Kingdom arose from the agencies, long
before the fossil record. All the major invertebrate
groups have marine representatives and some (stinging-celled
animals, such as corals, anemones, and gorgonians; spiny-skinned
animals, such as sea stars, cucumbers, and crinoids)
are almost exclusively marine. All of the animals that
eventually turned to freshwater and the land originally
came from the sea. (that's by belief anyway)
Most
of
the non-vertebrates of interest to marine hobbyists
reside in intertidal to shallow water habit since. There
is a rich diversity of species there, some living freely
in the water, others living or wandering on, in, or
among the substrate, and the rest attached to the substrate.
With live aquariums all modes of nutrition are employed
-- there are carnivorous, filter, suspension, detritus,
and deposit feeders -- some relying to a degree on symbiotic
relationships with microscopic algae, and all ultimately
depend on algae for food and oxygen.
Each
of the marine invertebrate groups in a live aquarium
have structural peculiarities and specialized terminology.
Don't feel overwhelmed by this; Skip the classification
sections if you aren't ready for them. What is that
we are really concerned about? Keeping these things
alive. I apologize if my opinions may vary from yours
or others when I discuss live aquarium species. There
are freshwater species and plants that are of course
live inhabitants. For the purposes of this web site
salt water inhabitants are discussed when referring
to live aquarium.
Spineless
water urchins, or invertebrates, are more difficult
to keep alive than fish. Many invertebrates are highly
dependent on stable water conditions and will quickly
shrivel up and die in live aquariums that have seemingly
healthy populations of fishes. Most aquarists shouldn't
even consider keeping invertebrates in their live aquariums
if their water skimming isn't the first rate, their
circulation is sluggish, or their key measures of water
quality or not an order.
