I have a 210G I am stocking and am considering Clown Loachs. After reading the profile on this site, it said that a max size of 12" is attainable but they raraly reach half that size in an aquarium. Can anyone that has owned them for some time verify that? Id like to get 3-5 of them but dont really want to devote a good chunk of the tank to them if they were to actually hit 12".
