Bristlenose Weird Colour?

[sangah10]

I noticed that my 2 bristle noses go to a very light colour sometimes. I just did some redecorating and they seem to be very light in colour. The tail is a tiny bit transparent..they appear to be acting normal and stuff.

they go darker to their normal colour again after a while, but even if i dont do redocrating or anything sometimes it just happens randomly. is this normal?

what is it ?

is this bad ?

colour change is usually reflected in stress, BN's and commons/gibby's tend to be the most common on seeing the patches, but colour changes can be caused by water quality i think its excess mucus growth or somethink like that.

I have noticed mine are darker when rasping on bogwood but when on sand substrate the colour appears lighter and some patches can be seen on the head area. I thought it may be a blending in to the background kind of thing. They always show light colours (alot lighter) if I am moving them or rearranging the tank.
