@curtism1234 Definitely there is some temperament considerations, too. Are you the guy that will pay $5000-$50,000 to chuck flies in New Brunswick, Labrador, Quebec or Russia trying to catch an Atlantic Salmon? That is absolute heartache and limited results! An amazing trip would be two fish. I've never caught one, just funded their tourism industry and shed a lot of tears.
Now if you want action, yes you can do peacock and have a blast. We can also meet up for the price of a case of beer in Miami and fish the canals and ponds catching tons of peacock bass as they are invasive about everywhere. Going to South America to fish for peacock is another matter, but it is really about the travel expense, not the glory of the fish. (rooster fish and others are usually included and actually are more exciting) But again, if you want to go to the amazon its really about the location more than the fish.
Now back to the tigerfish. They can break your heart but not like a salmon or even a steelhead will. If you are planning a fishing trip you'll go at the perfect season for awesome action. If you go during hunting seasons you are probably going to have a so-so experience. I think in maybe 8 hours of fishing here and there during the safari downtime we caught around 8 or so tigers, either 2 or 3 of them by me on a fly and the rest on conventional tackle. This was during cold season where action is supposed to be rather poor. So on the spectrum of prime walleye or bass fishing with one in the boat every 5 minutes, and horrible odds salmon fishing where one in 14 days is amazing, tiger fish in Africa is certainly not bad odds.
The reason you don't see more of it is that it is really, really expensive logistically to get you to the Tigers, not because its boring or hard. It costs almost as much to outfit a fishing trip as a safari and most people won't drop that kind of coin on a fishing trip. That's why I encourage you to consider it on your safari as you're already there and paid up, give it a try. Especially so if you don't think you'll ever come back to do a dedicated fishing trip.
