Thanks again for visiting us here at the AroAquaticWorld site. I really hope that you will find some interesting materials here. I have been in contact with numerous parties here in Singapore and overseas to see what, so-called non-mainstream arowana and other fish books I could find out there. I must say that it's pretty amazing what you can find out there if you look hard enough. I have found some pretty amazing stuff and would like to share them with you.
Most of the materials that I have found are not new at all and I won't be surprised if some of them are not in print anymore. These are true gems if you asked me! Anyway I will leave it up to you to decide. Get your copy now as I do not know whether I will be able to replenish any of the materials after they are sold out on my site! I'll try but no promises. I will keep adding materials if I find any more interesting books out there.
Please do also read My Personal Rant before you continue as these are my personal observations about the books I found which I hope will help you in your decision.
