chen, lol yea the loach is always in the same spot. takes a swim from time to time but always back in his fav spot. the only time i usually see him swim is during feeding time only haha. lazy loach.
brandon, the big bds and little bds are in different tanks. when i added a 9 to 10 inch bd with the big ones a few months back, the big ones nipped at the new ray for a week and stopped. i guess thats how they welcome the newcomer lol. i also find bds are very nippy. especially smaller bds when they are hungry!
