ive read in an article that some bta's will lose their bulb shape, and that their is not much studies on why they do so. but just to make an empirical observation, i just wanted to know how some of you (who have bta's that have maintained its bulbshaped in the aquarium) maintain your bta's e.g. aquarium lighting, bta location, feeding, and etc.. i just like to say thanks to the people who reply to this topic..
