I would like to observe more aquatic species, but I live in Delaware, US, and the water quality isn’t great and most freshwater locations are not considered safe to swim in, due to pollution, bacteria, toxic algae, etc. The water is also not very clear, but fish can sometimes be seen in shallow water in sunlight. I always take a picture when I see fish, though. I have 34 local species. Any recommendations for observing more fish would be appreciated!
