Hi, I am new here. I need help with what predatory fish (fw) is good for a beginner. I want to keep a dorado. To clear things up, I have never done maintenance or water changes with tanks (my dad does them) with tanks (yes, it's the truth, the embarassing terrible truth) but i will maybe be on my own here, so i will have to learn to do those things, I have plenty of training to do. I will have a 3 meter long, 2 meter wide, 1 meter tall tank in about a year or more. For now i can only plan for the future, and i need suggestions on what can be a good practice for a dorado ( salminus sp ). I have no tanks in my current house i live in, so once again, i can only plan. I did not get so much luck in the other characins section so here i am, confused, desperate, lost . Btw i like fishing
