Look out when you buy new shrimps!!!

Recently I bought those ready-packed-and-go sakura shrimps from LFS. Everythings seems normal, until I put the whole pack into the tank, for the shrimps to get used to the temperature, saw a DEADLY HYDRA inside.

Most of us will be too excited when get new shrimps and forget to check the water. So far I had encounted snails, planaria and lastest hydra. Lucky I manage to notice it before it get into the tank. It'll be deadly or troublesome if it get into your tank.

Other than those ready-packed-and-go, even if it's those that allow you choose yourself, just be extra careful when you scoop the water, as hydra are so small, sometime it may be hard to notice.
