Cavefish can be obtained by preparing a raw cavefish on the preparation table whilst having a knife. Preparing cavefish requires level 20 Cooking and grants 23 experience when successful. Players may ruin the cavefish during preparation, resulting in a ruined cavefish; the chance of failure while preparing these will decrease as players reach higher Cooking levels.
Cavefish stop ruining at Cooking level 45 with the preparation boost.
^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.
