Often at night and first thing in the morning I see one or two of our tetras swimming almost vertical in the water, and they all go a darkish purple colour. Sometimes they are very pale and colourless, but as soon as the light comes on they swim normally again. During feeding times they are of good colour and school together.
Are my neons sleeping? Do any fish sleep?
If not, tell me whats wrong as I'm concerned for my little Mike's!
