What can I do to get over my fear of aquatic animals?

The fear of fish in general is called ichthyophobia. It's a rare and largely unknown phobia. It's possibly it's not the fish you fear, it's the size and dangers associated with them. Perhaps a TV show or a personal experience started this phobia. The best way to get over it is to realize the animals aren't bad. They're living creatures, just like you and I. Associate the animals with something good and happy instead of something fearful. Maybe the best treatment for you is to get face to face with your fear. That has worked for plenty of other people. Hope I helped! :)
