Currently level 21, is there any more to this game? Update: 10 more minutes of playing, now level 24. The game gets laggier and more prone to crashing the more fish levels you increase. Most fish are now at level 100. Reduced star rating due to the game becoming very laggy and unplayable at higher levels. ### 5/5 — Yesss!! *2020-01-07* I really hope this Game is like an aquarium I rate 5 stars!!!!
