This makes me laugh. If you keep a good tank. And have common sense these fish are no problem. I have 2. And hell my one I had to take out of the tank due to the big one trying to eat it. And I literally set up a 10 gallon tank in 1 night and my little one has been living and eating and growing fine in it!!! People just have no common sense any more. Also Taksan is the go to guy for tigs. Any question he knows and was a great help to me. Only thing I must say is my rigs coloration isn't perfect white and black
