Swarm of young striped eel catfish create hypnotic schooling underwater

"One of the most charming encounters you can make underwater: a swarm of juvenile Striped Eel Catfish. The dynamic of these schools is enchanting, and I will never get bored watching them rolling over the sandy sea floor. In their early life they tend to form these vivid balls for reasons of protection but also to feed together. Fish in the front will move down to the sand and grab some quick bites while the remaining school is flying over them. When finished, every single fish has to get in the line again and the show starts from the beginning. Wait, roll, eat, repeat! ☝🏾😁"
