In the laboratory under artificial domestication conditions observed marshmallows behavior, feeding, growth and irreversibility and other characteristics. The results showed that, under the conditions of high and low light conditions (25lux), the mall was fatal to each other when the density was high (more than two encounters). Carnivorous, long-term feeding the same kind of fresh meat anorexia, like eating water earthworms, freshwater shrimp and fry. The optimum growth temperature is 22 ± 0.5 ℃. The average body weight of 18.87g mall fat 鲵 45d after starvation appear irreversible point.
