So I am currently trying to raise some Icthyosaurus and have noticed that after some time after initial spawning, they seem to just stop moving and sit at the bottom of the river bed. I even have installed some bubble blowers and moved them near the to try to remedy this but it has not solved much. I should note that they do this even after I have fed them. Any help??
