Raw rocktail

Raw 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. The player needs a normal fishing rod and Living minerals as bait to catch Rocktails. The Living minerals can be obtained from a living rock protector's/striker's/patriarch's dead remains or they can be bought from the Grand Exchange. Level 73 Mining is needed to mine the dead body. The Living Rock Caverns, however, are quite dangerous. Players could be attacked by level 120+ monsters. Fishing in the unofficial worlds for Living Rock Caverns (84, 77, 88) can be safer for an individual by spreading the creatures' attacks out amongst the group. Since 11 April 2012 it is possible to get a strange rock by fishing rocktails.

Fishing rocktails gives approximately 0 coins profit per hour with level 99 fishing, assuming about 100 fish are caught per hour.

They require a Cooking level of 93 to cook and give 225 experience per fish (228 when a dwarven army axe is wielded after completion of some Burthorpe/Taverley tasks). Rocktails stop burning with a Cooking level of 94 while wearing cooking gauntlets, and receive around 270k experience per hour.
