Tetra are a type of inedible fish that are offered at the mysterious altar in the Ruins of Camdozaal, granting 10 Prayer experience.
Tetra can be obtained by preparing a raw tetra on the preparation table whilst having a knife. Preparing tetra requires level 33 Cooking and grants 31 experience when successful. Players may ruin the tetra during preparation, resulting in a ruined tetra; the chance of failure while preparing these will decrease as players reach higher Cooking levels.
- ^ Offering fish takes 2 ticks on the first offering, or 3 ticks for every subsequent fish that is automatically offered
- ^ 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.
