I just want to add that I have a young silver that I began feeding plankton and small sized trout chow after I first bought him at about 10 cm. I donít know what he was eating at the fish store, but he didnít take long to accept this food. Heís now 20 cm and very healthy and robust, but will only take the trout chow. Iíve tried feeding freeze-dried krill but he wouldnít take it. If youíre not familiar with trout chow, it is a floating, round, brown pellet that is used (I think almost exclusively) to feed trout at trout farms. It comes in various sizes for different sized fish. This food is one of the more advanced, scientifically formulated fish foods in existence, so Iím not worried about the quality. Also, itís quite cheap. Of course, trout are carnivores (good) and not tropical (maybe not-so-good) but I tell you, this fish is thriving! I will try to feed more variety soon - maybe some crickets or goldfish - but Iím in no rush. My point is, you can train young silvers to accept prepared foods and avoid some of the pitfalls of live foods (i.e. cost, parasites, viruses, etc.).

I bought one Silver Arowana two years ago and it felt so great because it's a rewarding experience. I bought it at about 16 cm long and it is awesome how this fish grows in such a short time. Today my Silver Arowana is about 60 cm long. I think it's growing about 3 cm a month. I advise hobbyists to put a tight fitting hood in their aquarium, as this fish tends to jump because they are good jumpers in nature. They can jump about 1 meter in the air. In my observation, their sexual differences (in case you want to breed your Silver Arowana) are: the male has elongated lower jaw and has a large anal fin. The female's lower jaw is equal to the upper jaw, and has a deeper body and diameter.

I am with you ladies and gentlemen all the way. Osteoglossum is, to my mind, the King of Aquarium Fish. One very important point I have noticed is the need for live invertebrates, e.g. crickets and grasshoppers, to be included in the diet of baby arowanas. They bring out the colour, make them work for their food, prevent "droop eye" and finally you can gutload the crickets with high quality foods to enhance areas of the specimen that need work. For example, body mass or colour...etc. I base this on having kept a lot of arowanas in my role as an aquatic store worker. Keep up the great love.

This is my favorite fish, very beautiful, and majestic. Despite the S.A's reputation, mine is the gentlest fish in the tank. He won't even try to eat the smallest fishes in my tank, because he was raised on commercial diets his whole life. During feeding time he'll be the first to strike at the food with great eagerness, kind of like a grenade exploding in the water (one time he splashed about a quart of water onto the floor and on me). At 65 cm long his 680 liter tank is getting smaller, and I hope to get him a new 1400 liter custom tank soon.

I have had a Silver for about 2 months now. He is in a 110 liter tank. This summer 2005 I am getting a 950 liter tank for him. He is currently 15 cm long. I feed him Krill, Raw Shrimp, Minnows, and Crickets. He is owner responsive and he is the most interesting fish I have ever had. I have 10 years of experience as an aquarist and he is no beginner fish.

Arrowana are a very beautiful fish that are said to bring you good fortune. These fish are also very delicate fish that take a lot of patience to take care of. I worked in a pet shop and taking care of these fish had proved to be a very difficult yet rewarding task, because they seem to gain confidence in the care taker. They jumped every time my co-worker would try to take care of them, yet seemed to come peacefully into the net when I put it in. Also, some believe that the full moon affects the behavior of these fish.
