Put the tank light on this morning and my 4 neons were pale , they seemed to be getting their colour back but I had to go to work so I won't see them for 12 hours now ...
*giggles* reminds me of my early morning panic stricken water change and testing. As already stated, perfectly normal. It's like the blood in our body doesn't keep full flow to the parts we don't need when we sleep - it's the same with fish. My neons look deathly ill first thing in a morning, and they always look at me as if to say "awww mum! 5 more minutes!"
Reminds me of a week or two after my fishless cycle on my first tank, awoke one morning to find my Neons all 'pale'..cue a mad rush down to the shed for bucket and siphon.."what on earth is wrong with you?" asked Mrs.Apple.."my fish, they're dying". But no. A full set of water tests and a 50% emergency water changed proved it was totally natural.Lesson learnt.
