I noticed a few days ago that one of my Tiger Barbs color had started to fade a little bit. After I got home from work today and looked at the tank, I noticed that some of the other Barbs have faded a bit as well. One has faded a lot! The black lines are very faint on him (or her). I have 6 of them and I've had them just over a year, I think, and they've never looked like this before. Anyone have any experience with this and/or know why this is?
Also, here in the last couple of days, I've noticed the smallest Barb of the 6 has been really picking on my CAE
. He doesn't nip at him but he will just nudge him over the back... just pestering him. The CAE
usually doesn't move or even seem to mind but it has to be annoying. Is this a problem?
