Our leap into keeping fish happened when my son adopted a small tank with a goldfish called "Frank" who looked like he had been through a wringer from someone who couldn't be bothered looking after him anymore. He had a bulging eye and a distended tummy.
We thought Frank was lonely so got him a friend "Zippo" and they grew to the stage where there was no room for them to move anymore So that brings us to now - we have just upgraded to a 75 ltr tank, cycled it for a week and checked all levels with the pet shop who told us to add a bit of this and a bit of that and get the fish in there ASAP as she was surprised they weren't dead living in the small environment
Anyway things are now turning pear shaped. Frank has become quite lethargic and sitting on the bottom of the tank and Zippo has become quite erratic chasing Frank around and just generally racing around the tank hitting things. He also has started getting white patches on his body. I've read about Ich but I have no idea what I'm looking at. Also today white dots have started to appear on plants and filter in the tank. Can anyone give me some incite as to what is going on please? Have attached a photo but not sure how to attach more.
