here we go:
A similar arrangement is often said to exist for the beautiful Periclimenid shrimps living on sea anemones throughout the tropics and well illustrated in these images. Here the shrimp is presumed to get the benefits of protection while the anemone gets no benefit whatsoever (See, for example, Mihalik and Brooks, 1997). These relationships, however, may be significantly more complex than this simple explanation indicates. Some of these shrimps, such as the relatively common Periclimenes pedersoni, found throughout the Caribbean, may be a cleaner shrimp (Zann, 1980). So, while the shrimp may be a commensal on its anemone, it may simultaneously be involved in a mutualistic relationship with some of the fish in its community. Yet other species of Periclimenes turn the usual shrimp and anemone relationship onto its head. Fautin and her coworkers have recently shown that Periclimenes brevicarpalis, which is found on the bulb-tipped anemone, Entacmaea quadricolor, in the Indo-Pacific, grazes on the anemone, eating its tentacles (Fautin, et al., 1995; Guo, et al., 1996). So, in this case, the shrimp is not a commensal but an ectoparasite.

Robert, bei "meinem" Händler sollen die noch teurer sein. Er redet allerdings immer von yashIa und nicht von yasha. Diese S yashia sind wohl seltener auf den Stocklisten? Ich bin ziemlich verwirrt und werde noch mal googeln. Das Bild von Dir habe ich, meine ich, bei einem US-Händler als S yashia gesehen.... 
Da hab ich heute einen vielfach höheren Preis gehört....
