Are zebrafish poisonous?
The results showed that prothioconazole exposure to zebrafish embryos produced a series of toxic symptoms, including hatching inhibition, shortening of body length, pericardial cyst and yolk cyst. In addition, prothioconazole exposure caused significant lipid peroxidation and oxidative damage.
How many years can a zebra fish live?
In captivity, zebrafish can live over 5 years, however generally they live for 2 to 3 years, and grow up to about 65 mm long. They are an omnivore, feeding on the small organisms found in the slow-moving waterways where they favour living.
