Well it's a right mess Wilder. They fell for the LFS selling them 2 goldfish and a bowl about 10l with no filter. I convinced them to get a proper tank so they bought a 64l with filter.
They know it's not a long term home for goldfish and they have a pond to rehome them in about a year.
They are 'normal' goldfish, not fancies, maybe 2-3" long.
They've only had them a couple of weeks. They aren't up for water testing etc, so I advised to change 50% a day. I went over and tested ammonia for them tonight though, as the fish had been lying on the bottom, and it was either 2 or 4 ppm!
They changed 50% straight away and I advised another 50% later tonight.
The spots don't look like salt, they're larger, more fuzzy looking. The film is just like something that catches the light, you can still see the fish's colour underneath it. No fluffiness to it at all.
I advised them to put the heater in that came with the tank and gradually get the temp up to about 25C (it was about 20 with no heater) and I added a dose of myzaxin until they can get meds from the shops tomorrow. No worries about the filter bacteria, there'll hardly be any yet!
Can't get pics or anything as I doubt they'd hold still for one thing but also I'm home now and not going to go bothering them with camera etc
