In my tank I have 2 lineautus a rhomboid, beauperryi, a mckossers, 2 lubbocks male and female, and a scotts supermale. My earlei which is on his way as well as a pair of flame, also on the way is the rare 8 line flasher wrasse which i've been waiting for, For sometime now with my experience each has its own symbiotic relationship with the others while one flashes at the other another one runs and hides. My scotts seems to be one of the kingpins in the tank and my Rhomboid likes to disappear. I also have a 4 inch purple tang in there i have a custom 160 gallon cube 4 sided starphire glass tank. I couldn't agree more with Marshall O and Eatbreakfast you can put quite a few fairy's in your tank but you really have to decide which are best my Lubbocks did not like eachother at first and chased one another around like cats and dogs I thought day one i was gonna go to bed and wake up to a carcase. However its not always about the nicest most expensive ones you can get there are some beautiful wrasses out there that are not very pricey either I just love them because they will never go after my coral and their gorgeous fish. But I always qt my fish with prazipro i've seen alot of fish especially fish that are sand dwellers or diggers get infected by parasites or worms that lay dorment in sand beds. Side note blood worms for me are an occasional snack we feed them bloods maybe once a month otherwise its my own blend. however since the addition of the purple tang they all seem to go after the seaweed clip now which i find strange anyone else experience this with their wrasses?
