My Friend gave me this guy yesterday because it was his last fish and he wanted to take his tank down. Its almost 5.5" and he said hes had it for 10yrs. Ive never kept these guys but im reading they should be in groups. He was in a 20gal tank all by himself hiding under a decoration but now in my tank hes all over the place and i havent seen him hide once. So i guess my question is - do i really need to add 2 more or is it not a big deal because hes used to being alone? and if i did would the chances of fighting be higher since hes never been with other CLs?
