Attack of water snails and others

As you can see, the log had been attack by about 20 to 30 water snails.

The picture above shows a damselfly nymph. It was found dead outside our fish tank.

*The pictures might not be clear. We are sorry for the low quality of the pictures.

After the school reopens, we had found out that our system had been invaded by the water snails.

There was about 100 water snails found living in our fish tank.

For the safety of the fishes and the system, we had changed the water and the gravels that had alot of water snails living in it.

Till now, the almost all of the water snail had been removed and the tank is clean for the fishes to live in.

We had planned to get 2 more new aquatic plants to replace for the ones that had been invaded by the water snails.

More information about the attacks of the water snails will be stated in the next post.
