The following is from Wikipedia:
“Ichthyophobia is the fear of fish. Although the term technically refers to a specific phobia, in many contexts it may refer to any kind of fear of fish, such as fear of eating fish, or fear of dead fish. Galeophobia is a subtype of ichthyophobia specifically focused on one species: sharks.”

Since “fear of eating fish” is mentioned fear of swimming with fish would fall into the same category. The article is fascinating and quite informative…if you want to read on Ichthyophobia.

I can more than understand that many not liking to swim with fish. It wasn’t until I became a scuba diver that I realized that it was more of a fear of not seeing them while swimming and having one nip at you. Now that I scuba dive I am no longer worrying about what’s below me because I can see them under the water on a more face to fish level. I also don’t eat fish and consider it as a sign of good faith that they won’t eat me LOL. To top it all off I have been teaching scuba and snorkeling for 25 years and currently work at a scuba diving facility, Visibility Unlimited and have come to appreciate the fish a lot more than I used to.
