Rocktail

The Rocktail is a fish that is found in the Living Rock Caverns. Rocktails require a Fishing level of 90 or higher to fish and give 380 experience per catch, which is the most experience obtainable from a single catch of any fish in Runescape. You need a normal fishing rod and Living minerals as bait to catch Rocktails.

Rocktails require a Cooking level of 93 to cook and give 225 experience per fish. Players stop burning Rocktail at level 99 while wearing cooking gauntlets.

Rocktail heal 23 hitpoints and can heal you up to 10 Hitpoints higher than your maximum. This makes it the best single-bite food in the game.

Eating raw rocktail (using the bunyip swallow whole scroll) does not currently give over-maximum bonus hitpoints. Please note that the caverns are quite dangerous - you may be attacked by several level 120+ monsters that live there. It is currently possible to make a profit by buying Raw Rocktail, cooking, and selling; you are, however, likely to burn quite a few.

Trivia

 * Even if your Cooking level is 99 you can still burn Rocktail; however, Cooking Gauntlets can prevent this.
