I want to create a mostly cp vivarium. Anyone have an idea whats a good starting place. I dont know what other plants to use, what animals to add, how to build one, how to do air and water circulation, ect. I have a 20L tank with two twin 40 watt bulb flourcent lighting fixtures. I have a couple of cps i want to include (N. Llowii, N. ventricosa, d. capensis typical and red, d. spatulata and several others i was thinking of getting) Other than that, im lost. Any advice, websites, ect would be great.
