I am aware of the GT's and Aro's personal issues. The GT will be sold when he is around 6-7" and the aro is also a temporary inhabitant. I look at it like this, I love fish, I like getting to know a certain species, if I can buy a fish for say 10-15 bucks, watch him and enjoy watching him grow than one day I will sell him when I cannot help him anymore for say 20-30 dollars to a more suitable set up and that is worth it for me. I also picked up a red zebra today. agression is not existent at this point in time.
