This is a cool fish that you can get at a decent price. I have only had mine for about a week and he is taking some time to adjust. You will read about how much they eat and how active they are, but when they are stressed they let you know very well also. Mine likes to stay out of the light. As a matter of fact, the only time he will eat is when I have my tank lights off. As soon as I turn my lights off, he goes hunting. He does not know me yet and he will not eat when I am close to the tank; he is also very young. This is just my fish, maybe you will get a more sociable one. He is getting better though; he just seems to be very cautious. Remember, these fish come straight out of the wild, so be compassionate cause they are going through a big change from sea to tank. Also, don't throw in a lot of food to get them to eat, it will ruin your water and it will not help them eat any better. They know what to do when it's time to eat. Don't give them more than two feedings each day and no more than the other fish are able to consume if they don't eat.
