So we do not have any bottled watter for a new betta (sushi), we heard that you can use tap water as long as you leave it out for awhile. We left the tap water out in a clean container for about 12hrs and then switched over the water. Sushi no longer looks very energetic. My main question, is the fins of Sushi do not floats outwards, then actually just sink downwards, is this a sign of it being sick or could just be, i dunno, tired?
