so i just read a post about discus being stunted and i was a little confused. what does a discus being stunted actually mean and can it be fixed. also i just picked up these two discus from my LFS are they stunted. they swim around fine all day and they are eating like champs any info would be great. also if someone could identify them that would be great i was told they were a red turquoise discus and a blue diamond is this true
