Answer
Hi David;

If the fish comes out to feed and swims normally he is probably fine. Salmontail cats are nocturnal but they will adjust to daytime activity. The active one is probably just less shy for some reason. Watch the shy one to be sure he isn't being bullied or isn't sick.

Keep in mind that these guys will eventually get almost 3 feet long. Here are some profile pages about them;
