Archer,
Well said. I have kept tomans before, up till they were about 1 1/2 feet long and released them. Their behaviour is the same as you mentioned above. But what i am trying to do is to present the haruan i have with baits that we use to actually catch them. Sure, i have caught haruans on seluangs, but that was a by product of me tarponing. I dont think many people will use live fishes to catch haruan, considering the terrain the live in. What i hope to do is find out what they actually do before striking. I think by finding this out, we can improve our haruan fishing very much. Also, when they are hungry, the haruans will readily take bait that is even bigger than their mouth can handle. This i did 2 weeks back. Didnt feed the haruan for a week, (4ft tank, with 4 puyu[palm size]). After a few days, a noticed one of the puyu dissapeard and the haruans stomach bigggg!!!. The size of all the puyus are definately not even close to the size of the haruans mouth, yet it whacked it. Anyway, i am hoping to hear from your observations. It will definately help.
Marlin, im waiting for your writing!!! Eagerly waiting!
Snakehead86, i dont see a reason why haruans make the water slimy and dirty. Like arowanas, tarpons, and many other fish, their droppings are solid, unlike most cichlids, which will make the water murky in very little time. Also, based on my personal experience, if they are trying to jump out, something is wrong with your setup. I cant say what, cuz i myself have faced this problem , and after changing so many things(too many to remember), the haruan is ok now. The easiest method would be to increase the aquarium size and reduce the water level. This way, it has sufficient area to swim around, yet will not be able to hurt itself even if it tries to jump. Another word of advice, dont try to keep 2 haruans together(Especially if they were caught). The stronger one will kill the weaker one. No doubt about that. But if kept from small together, it is a totally different situation. they will only start to fight if they dont have enough to eat.
My rule of thumb for rearing haruan/toman: Make sure their stomachs are full at all times. If this is fulfilled, they will (most of the time) be peaceful towards other members in the aquarium, even if the other fishes are small enough for the haruan to eat.
Also: i tried another lure just now. Baby cima 40mm sinking minnow. As usual, took off the hooks, and attached it to some lenght of fc (this time in daylight). i let it sink right in front of the haruan. The haruan became fixated to the lure. I made extremely slight movements, and the haruan just followed along. As if it was hypnotized. But the second i made an erratic move, wham! Very interesting. Have to do much much more trials to be able to come out with someting useable to catch them. Hopefully i can study them and come out with something useful!
