Funny this thread is here tonight. I have read a few time's not to wear red around an aro tank, and tonight when I went to feed my lil guy (8") he was acting weird, jerky movements, and resting on the bottom of the tank. Now that I saw this posting I realize that I have on a red shirt. The shirt may be the reason or it may not but I have seen loads of red color scheme's and fish stocking with aro's and they seem to be fine. Imma do a water change anyway.
