I had his mirror in this morning so I saw his gills well, after he wouldn't eat i figured maybe he was bored so put it in to get him to play and they were his normal red.
I got him on Dec 6, 2010 from my local Petland.
At first I was changing his water only about every 2 weeks but was doing 100% water changes, then I found out I am only supposed to do about half the water only because some bacteria in the water is 'good bacteria' and the water can actually get dirty faster if I'm always doing 100% water changes, which yes was seeming to be true, it seemed to get dirtier faster every time. So now I plan to do 50% water changes once every 3-5 days. Is that a good amount of time?
...hope I answered all of your questions ;0)
Thanks so much for the help!
