While transferring the fish from Main tank to other while cleaning, it's
recommended to us Aquarium Net. Avoid catching fish with hand.
Fish will get affected through it.
If you are maintaining more than one aquarium, use Separate net for
each tank, because using the same net to all fish tank will spread the
diseases to other tank if any one tank had been affected.
Note:
1. Don't shake the Net while fish is inside, fish wings will be get
damaged in net holes.
2. Don't use Small size Net to big fish.
3. Don't keep the fish in Net more than 15 Seconds.
