sorry but its a fresh question... I've had this guy for 4 months now. a few weeks ago i noticed an area on his side where his scales seem to be rotting away. he eats like normal. he's shy by nature. any ideas as to what it is? pics coming soon. all params are good. tank mates: 1 other bloodfin and 4 neon tetras. ill be adding 3 more bloodfins soon if all is well.
