A very good way to learn a lot about fish. Keep watching as things will change soon. If the LMB live for 60 days you will have done well. As they all get a little bigger look for drastic changes in their aggressiveness. When you have watched for about 2 mths then try this. Find a red laser pointer. Turn the room lights way down (but not dark) and wait 5 mins., then shine the red dot on a fish and watch the show. \:\) Also watch for color changes in the fish and note the reason you think they changed color. Tell us what you see.
