Hello telboy the wrasse was 6 inches when I bought him and has not grown since , he had been kept for a number of years ( dont know how many ) in a very small tank when growing up resulting in him having a bent spine ,according to the owner of the shop I bought him from . felt sorry for him (all heart lol) didn`t buy the fish I went to the store for,had him instead . Since he has been with me he`s straightened up quite a bit and can now turn left and right without any problems hes still a bit crooked but a lot straighter than he was. hes totally unafraid and would also come into my hand whenever I had my hand in the tank or at feeding times, AS you know these fish are an entirely different colour when young and only turn into the colour he is now in adulthood so we still cant guess his age by size. brian.
