Has anyone tried to interact with their puffers or train them besides at feeding time? I know this seems like a weird question but I really want to play with mine lol. What I mean by that is I know they are intelligent creatures and they make those little soccer balls for fish tanks. Has anyone actually tried this for saltwater? And/or how do you interact with your more intelligent saltwater fish such as porcupine puffers. I heard about target training puffers too. Has anyone had success with it? https://www.usatoday.com/videos/new...ores-epic-goal-soccer-themed-tank/4938229002/
