fish poop

[cheken]

hi can anybody advise on fish poop?

does it normally change colour from time to time i always thought that it was black!

i have 5 platys 3fmale 2male,
7 guppys 5fmale 2 male
i am feeding usual stuff like flake, bloodworm etc and only ever enough to last 3 mins i feed once daily.

the water tests seem tobe ok too.

any advice would be helpfull!

regards

Gareth,

Well shades of brown, black and green ish are ok. White is definitely not ok as that usually indicates internal parasites.
