very easy to keep as long as you have a big tank, big filter and lots of food. My adults can each eat about 150 grams aday of meat, so u need a wicked filter to cope with the ammonia. For a single motoro you will need at least a 6ftx2ftx2ft tank, but ideally this will really need a sump of the same volume, this is quite small thought for a single adult, so better 7ftx3ftx2ft. I would recommend people not to get one, as really i would recomend 2 rays together, thats an awful big tank.
