Own a Fish Pond Rain Event
The Rain Event is the most frequently occurring weather event in Own a Fish Pond. When rain particles appear over your pond, every growing fish receives accelerated growth and a 0.3% chance to mutate into a Rainbow Fish — one of the most visually distinctive and valuable variants in the game.
Rain Event Mechanics
Rain triggers randomly without a fixed schedule. There is no in-game timer announcing the next rain. Visual cues include rainfall effects over all three ponds and darker ambient lighting. The event affects growth speed globally, making it a good time to hatch new eggs even if you miss the mutation roll.
Rainbow Fish Mutation
Rainbow Fish display prismatic color cycling and sell for significantly more Bubloons than their base form. The 0.3% drop rate means you need many growing fish simultaneously to expect a Rainbow proc. Statistically, placing 20+ fish before rain begins gives reasonable odds over multiple rain cycles.
Rain + Coral Combo
During Rain, there is a 10% chance the Coral Event also activates. Coral grants Shiny mutations at a much higher 30% rate. A Rain-Coral combo is the best natural mutation window in the game — prioritize opening Buckets during these overlapping events.
Farming Tips
Stock all three ponds before rain begins. Use egg-laying species to maintain population density across rain cycles. Avoid selling fish mid-event — let the mutation roll complete before harvesting.
