yeah mate, near as i can tell these stools were from a blue diamond that went down hill after an asian red turk was introduced to the tank (after a 4 week quarentine).

will try and get more photos of the 2 fish in question, i saw the red turk passing white stools last night, buts its a good size and healthy, eats like a pig, but isn't the biggest fish in the tank (the way it eats you assume it would be I guess that should have tipped me off).

It got 2 doses of levimenisole while in quarentine 3 weeks apart, i guess i didn't break the cycle, wont make that mistake again.
