I've had Freedy for about a year and a half now. A few weeks ago, I introduced some some small spotted ramshorn snails into his tank from a different aquarium (the goldfish in there appeared healthy and had been there for some time as far as I know. I took care of it, it ate like a pig). I then fed him some bloodworms as a treat, and a pellet. He got constipated, so I fasted him a few days. He did unclog himself, but his poo was encased in a strange white coating. It's been two days, and it still looks like that. He still acts and eats like normal, although I've been feeding him less as a precaution. Could he have a parasite? How would he have gotten it- from the snails, or the bloodworms? I've had to leave and I'll be gone two more days- if it IS a parasite, will it be too late to save him by the time I get back?
This comes at a very bad time... I finally managed to cure his persistant finrot and tail biting (it's grown back beautifully), got him a brand new five gallon, and bought him some aquatic plants (anubias nana, they're also in the tank). I'm about to go on a two-week visit to some relatives, and I'm already traveling right now. If he suddenly gets worse, I know the people taking care of him for me won't know what to do... and I don't want to kill the plants with harsh chemicals!
