角蛙幼崽饲养技术
Raising the TadpolesAfter the eggs are laid, the male and female can be moved back into their separate tanks, and should be cared for under normal conditions. The eggs should hatch in about 1-2 days.After the tadpoles emerge, you have 2 options. These tadpoles are meat eaters and quite cannibalistic. The first option is to separate all of the tadpoles into their own jars. This can be very time consuming, especially if you intend to raise them all (there may be several hundred).The second option is to place groups of tadpoles into large aquariums with lots of aquatic plants. When fed, they will swim for the food and then hide again. Pet stores like Petco and Petsmart in the US sometimes sell plants that aren"t even aquatic in the aquarium section of the store. Many plants will not survive in low-light conditions, so do your research.Some suitable plants include Anacharis, Elodea, and Hygrophila. You will certainly lose some tadpoles to cannibalism if kept in groups, but it is more feasible, and if they are fed regularly and well, losses to cannibalism should be minimal.The water should be changed very regularly (every day or two). Please note that if you leave tadpoles in a jar without changing the water, they are likely to die quickly. Tadpoles should be maintained at a temperature of 75-80 °F (24-27 °C). This can be accomplished using an aquarium heater.The tadpoles are carnivorus and require a good protein rich staple food. Frog and tadpole bites (a pellet sold at pet stores) are suitable but if uneaten they will foul the water quickly. You can also use live foods such as California Blackworms.The tadpoles will grow very quickly. In less than a month you will have your first Froglets. All Frogs drown easily around the time their front legs emerge, so they should be provided with very shallow water and there should be ramps, islands, etc, on to which they can climb easily.
You must make another difficult desicion at this point: if you leave the growing Froglets in a large tank, you will invariably see cannibalism. You could allow this, or you can switch to the hard work of keeping the Frogs in individual cups. These will require changing every day to avoid fouling and possible disease. This can be a time-consuming process, but very much worth it for the experience. You may even make some profit, if you have a willing pet store(s) near you or you sell the Froglets over the Internet.
