Default environmental terrarium

hi! That sounds like a good project. What sort of Terrarium are you thinking of.

Also, what are trying to observe? It's best that you have an idea - for an excellent example involving crayfish in an aquarium, and their response to light, see [url]http://www.all-science-fair-projects.com/project37_78.html[/url]

Here are some things that you need to know before setting up your Terrarium:

# Terrariums for mixed species generally need to be much larger than those for a single species, and are more difficult to maintain. Extra room is needed to provide the proper environmental conditions and furnishings for each species, as well as allowing each species their own space to hunt and interact somewhat naturally. Crowding different species together in a small tank can be a recipe for disaster.

# Carnivorous critters are usually not picky eaters, and will try to eat smaller cagemates of any species. This applies to animals (lizards, frogs, salamanders) that are largely insectivorous; most of these will not hesitate to hunt other small critters given the opportunity especially if confined in a tank with them. Also consider the stress you place on an animal, confining it in close quarters with a potential predator.

# Toxicity may be an issue with some frogs, salamanders, and newts. Many secrete mild skin toxins. These toxins may not be dangerous to humans, but they can accumulate in a tank and cause problems if absorbed through the skin of other tank inhabitants or if a cagemate tries to eat a toxic amphibian.

# Animals may become stressed by behaviors and displays that are unexpected and that they do no know how to intrpret. Between species that do not normally coexist, normal behaviors and benign displays may be misinterpreted, and this may lead to fighting or stress.

# Animals from different areas or habitats have differing immunities to parasites and infectious diseases. Therefore, one species may harbour a bug that it can carry with no ill-effects. However, if that bug (be it a parasite, virus or bacteria) is introduced to a species with no natural immunity, the result can be devastating.

Do let us know how your project goes!
