Is the fish eating normally?
If the fish is eating normally, then it's not an internal bacterial or protozoan infection and could be worms or food related.
Have you changed its diet in the last week?
A sudden change in diet can upset the stomach and intestine and cause weird coloured poop for a week or so.
What colour is the fish food?
White or light coloured food can cause light coloured poop. Liver problems can also cause it but are rare in fish. Dark coloured food normally makes the poop darker (eg: green food = green poop, red food = red poop, brown food = brown or black poop).
Long poop can be from the fish being well fed and just needing to do a big poop.
