Ok so well my fish the other day couldnt swim, that sounds really stupid, but its true. He kept floating to the top and had to keep swimming back down, its been 2 days and now hes fine?! I dont get it, do they just miraculously recover??
Well its 12 gallons with 2 goldfish. I can't afford a test kit, so I think im just going to stick to 50% water changes each day as it seems to have worked so far :)
I got 2 teeny weeny ones, they're filter has a turnover rate of 50-200 litres/hour a site said which is good for 60litre tank right? :D They're so cool :)
