Lost four fish today, 6 are weak and a couple more are swimming funny. Water tests showed that everything is normal. Population is 138 fish. Today I started switching fish over to their next food size, food #2 (their original food size was food #1). I'm slowly transitioning them from one food to the next, feeding half and half amounts of each food for the next couple of days before completely switching them over to #2. This will allow the fish time to adjust to the new food and give the fish who may be a little smaller a chance to be able to catch up by eating the smaller food. Everyone was fed at 10:00am, 3:30pm and 6:30pm.
