Something else I forgot to say: Every season has different creatures in the sea so it’s good to familiarize yourself with which creatures pay the most on each season and catch those creatures again the bubbles are a huge help on knowing which creatures are good and which ones are bad. For those creatures that are hard to catch and make you swim “forever” (usually the ones that pay the most bells) the trick is to swim above water and make that creature go against the net (swimming vertically not parallel to the net) and once the creature gets to the net it can’t move then you dive and grab it.I did most of my money diving for sea creatures. I learnt to distinguish (by the bubbles) which creature sales for the highest price and make sure I only catch those that pay the most. I go into the sea with nothing in my pockets and come out with all my pockets filled. I usually make over 100k+ on every trip.
