A guppy is a type of inedible fish used as an offering at the mysterious altar in the Ruins of Camdozaal, granting 4 Prayer experience. It can be obtained by preparing a raw guppy on the preparation table whilst having a knife. This requires level 7 Cooking and grants 12 experience when successful. Players may ruin the guppy during preparation, resulting in a ruined guppy; the chance of failure while preparing these will decrease as players reach higher Cooking levels.
^Auto-cutting is 2 ticks, then 4 ticks for subsequent fish. Opening the cutting interface takes 1 tick, so repeatedly clicking the offering table with the space bar held down takes 3 ticks per fish.
