Indonesian Exotic Tropical Fishes

I finally got around to Googling up this fish and this is some of what I found out It is a large knife fish that get to be almost 5 foot long. To large for most people aquariums.

I have been raising tropical fishes (freshwater) for over 55 years and I have not heard of the fish that you mentioned but there are many things that I haven't heard of in my lifetime. I looked in my copy of Dr. Axelrod's Atlas and it was mot in there so I will have to check my Baensch books to see if it is in one of them. I am trying to build a fish room for breeding freshwater tropical fishes and hopefully pay for the hobby plus a little extra. I am on the Board of directors for one aquarium club (and the librarian) plus I am the alternate delegate for the Northeast Council of Aquarium Societies for another one. I do not claim to know everything about fish because the more that i get to know about fish the more that I get to know that I don't know about them. So I am still earning about tropical fishes.
