Hi and Welcome to SimplyDiscus, To all newcomers to this site and this hobby, I recommend to go through the stickies’ in the Beginners Section and watch this video https://youtu.be/VXe3VKh7qF8 it is about an hour and half long but worth hours of information
P.S. A must read thread form the beginner section http://forum.simplydiscus.com/showth...ed-with-Discus
After this if you have any questions feel free to post them and I sure someone will help you out.
