Fish Sick or is this a MASSIVE poop?

[FishDoji]

We lost all of our fish last weekend except for our coral beauty. She has been acting perfectly normal since the others passed away. I fed her for the first time yesterday but I think it was too much food (trying to scale back the food).

today she has a massive poop (4-5 inches) trailing behind her. The poop is brown in color And normal consistency. Should I be concerned about a parasite or is this likely from a big meal?

Looks like internal worms/parasite. This thread will help:

That definitely isn't normal. Could be bacterial, or a protozoan (Hexamita/Spironucleus), could be a worm parasite (doubtful if you've had the fish for more than 4 months or so) or it could be idiopathic - just lots of mucus in the feces for no foreseeable reason (although it could well be stress from whatever killed your other fish). Is the angel still eating?

Have you determined the cause of death for the other fish? I'd be glad to try and work through that with you if not.
