You have to put the fishnet and remove out the fish from aquarium water. This low-density gas causes the fish to rise to the surface.

A majority of the Starfish species wont last more than 3 to 5 minutes out of the water and if exposed to the open air for so long they will surely die.

You can also add coral to your tank for them to eat. Usually, dissolved oxygen level ranges in the lakes from high to low, about 3 to 1. Do this until the container is full.
