What players say

92% of 8,223 reviews are positive · 87% of 94 in the last 30 days

Players praise the fish art, aquarium decoration, and low-maintenance background play. The most common complaints are that the buy-feed-sell loop is shallow and repetitive, progression is heavily time-gated, and completing the collection becomes a long randomized grind.
