I have two of them ex-amp, my realy nut case one is in a 125g with a bunch of africans, there is no way of cleaning this tank or putting your hand in without him attacking you and looseing control...
My other on is in a 90g with a jag, flowerhorn, and a 18" black shark! this one is really peaveful, it never attacks never bites any other fish..
As my g/f said, its just a risk, but is it a risk you want to take?? do you really want to loose your fish over a idea that most people are telling you that it might not work?? dunno dude its up to you!
Ex-amp 90g fish size: Red Devil 8" jag 7" flowerhorn 5"
The flowerhorn, just bugs them really. and lets face it, if they wanted to kill them, i think they already would of by now.. the G's are all about 3" with one silver one being about the 5" mark. And all these guys were in the tank with my nut case red devil as well at one point of time, but i had to take them out because he just kills and kills and kills when ver he gets the chance
