Ive had mine for about 4 months now, its about 4" long and is a pretty cool fish, sometimes he just sits about lazy doing nothing, then he will swim around and sit ontop of the bogwood abit. he tends to eat every other day and will ignor food if he isnt hungry, I have three garra ruffer fish in teh tank with him clearing up all the mess he makes and sometimes he shows intrest in them and gives chase
