Carnivorous plants are not likely to be found in the majority of your local fish stores. Obtaining these species can be somewhat difficult. If you’re either fortunate enough to live in an area where they occur naturally or unfortunate enough to find them invasively, they can be collected. Beware that in some regions these plants are protected—check with your local department of wildlife before collecting any plants from the wild.
Bladderworts may become invasive pest species in some bodies of water. As such, bladderworts—or any aquatic plant, for that matter—should never be transported between bodies of water, nor released into the wild. Also note that collecting in the wild greatly limits your selection.
Several online retailers specialize in the sales of carnivorous plants. I recently toured CarnivorousPlantNursery.Com nursery and Michael was extremely helpful with obtaining specimens to photograph for my article in the March 2013 issue . You may have to specify that what you’re purchasing is for an aquarium, or you will get a terrestrial form.
Many of the amphibious bladderworts can be encouraged to form aquatic stems simply by placing the pot, full of peat moss, into a shallow pan of water. Given a few weeks, the bladderwort will send stems out through the holes in the bottom of the pot. These will develop into the aquatic form.
