A cooked heim crab can either be found on the table at the start or by killing monsters in the dungeon and receiving it as a drop. A Raw heim crab can be bought from the Smuggler.
Other crabs in Daemonheim include the members only Tier 9 Blue crab, healing 220 Life Points and the Tier 6 Web Snipper, which heals 150 life points.
While progressing through a dungeon and if hurt, it is best to consume the Heim crabs first as they take up valuable inventory space but only heal 20 hitpoints compared to 50 by the Tier-2 Red-eye. This allows other, higher-healing fish to be put into the inventory. Many high level players do not take these off the starting table because they consider the 20 Life Points it heals too insignificant to bother picking up (it heals about 2% of the Life Points of a player that has 99 Constitution). Alternatively, they can be sold to the Smuggler for 72 coins, but are of very little use in a boss fight. The Jagex mods like to make jokes about Heim crabs just like they do with Cabbages.
If at low supply in dungeons, it is useful to buy heim crabs and eat them. It is because it is most cost effective among dungeon foods for healing in safe situations.
If you only eat Heim crabs during a dungeon, you will get the title "I Can has Heim Crab?" a reference to the internet phrase "i can has cheezburger?"

The word "heim" most likely comes from the word "DaemonHEIM". As Daemonheim means "Demon Home", "heim crab" may translate into "Home crab".
