Hello.
I have a few more (probably dumb) questions about my tiger barbs and TB's in general.
After looking around in the forums pictures for barbs, I noticed that between their stripes the color is like a creamy tan colour. Most of my 6 seem to have black spots in their scales. I don't think it's any type of disease because they are very active and healthy, but I just wanted to know if this was normal?
Also, I have 3 larger sized TB's, 1 medium and 2 small ones. Will this have any effect on them establishing hierarchy or is it a definite that the smaller one's will be the followers and the biggest one will be the leader? Should I just have gotten all the same size?
All of them spread out some times and do their own thing which I think is normal, but one of the small ones just hangs out by himself more often than the rest. Should I worry?
Okay, this is my last question I promise.

Is it normal for the TB's black stripes to change color to a blueish aqua color? I've recently started noticing this and I'm not sure why it's happening.
Sorry for all the questions, but I must learn! Cheers.
