I love bichirs I think they are super pre-historic looking and I really like that. I have one ornate and one senegal. Both at about 6". The senegal is the only one that is always swimming around. He rests at the bottom every now and again but for the most part he is active. The ornate is 99% of the time just sitting at the bottom. The one quality I look for in a fish before I buy it, it is active! Does anyone know about this? Is mine just lazy?
