He's still with us. He's in the 60l in about 40l of water with an airstone added yesterday. Still rests on the bottom a lot, but also has a good swim round now and then too. Very hard to see if he eats as he doesn't come to the top to be fed. I'm putting in a couple of grains every other day and presuming he's eating them. He's not so bloated but still a deformed kind of shape. It was 7th feb when I first noticed him, so he's been ill for a month and I've only seen him eat for definite once in that time.
I wanted to separate him to protect the other fish. Do you think he's 'safe' yet?
