Im trying to find another pleco for my 125Gal. Its only got a 4" royal pleco L190 in it with some corys and others, now the only reason im hesitant is in reading they say they tend not to get along with others of the same species and i have seen him chase a cory or two but not very often and hes fed very well (wife gets upset when all the veggies in the crisper dissapear) And theres 4 peices of malaysian wood in the tank and 1 peice of mopani, lots of hiding and plastic plants (i have silver dollars) but the other thing is it needs to be either tough or get a good size as a black ghost knife is on the list for one of the next tankmates. Any one have multiple plecos with there royal? How do they get along if so?
