i was thinking about either upgrading my community tank or getting a discus tank. i was wondering are discus as hard to care for as some people say? i've heard that they need almost perfect water conditions to survive, and they need to be fed speciality foods and stuff. do they need all this stuff? i was also wondering if i did get discus would i be able to move my community tanks fish into the larger aquarium? i have 2 balloon mollies, 2 guppies, 1 red tail shark, 2 scissortail rasboras, 2 regular angelfish, and a smaller sized pleco.
