Hi Tom, a warm welcome, nice to have you on board
Very interesting to have another member in Thailand. By all means ask all the questions that spring to mind, have you read all the stickies in the beginner section and watched the video? The fish on that sute look very nice, have you got any means of checking with local discus-keepers how reputable he might be? Purchasing good quality fish is of fundamental importance to the results you will get
