I have a Rainbow BTA that I have had for years. There is currently 6 heads. Recently I noticed there was 2 tight within the group that looked a little drab or less colorful than that of the others. I just figured those 2 were not getting the light that the others were getting and figured if they needed more they would move to get more. Well, fast forward a week or 3 and now I have noticed that one of the other ones near the front are not looking that great color wise. I have had the original in the tank for well over 2 years and have sold or given away probably 6-8 splits. I know the routine of these and know how they look. I'm just not used to this muddy green or brownish green color and kinda week looking tips. Maybe nothing to worry about. Maybe all is well. I just thought since I haven't seen this before and it seems to be moving from one to the other that it would be worth asking about. Hopefully there is nothing to worry about and I am just being overly cautious. Last 2 pics are from when they seemed to be looking better.
