They change colors constantly, depending on mood and development.
My single pair of bosemani rainbows produced many babies but I was left with 37 who are getting pretty big now. Parents are 3-3.5 inch male, and 2.5 inch female, the latter now passed. The brood are about 1.5 year olds and range 1.5-2.5". I gave away 20 and have the rest left. I need to continue culling them as it is too many in their 75gal. They display to each other, change colors, are already breeding but eating the eggs, and all change colors after weekly water changes. Cheers!

Oh nice you have a lot, have you ever experienced them with damaged lips? I’ll post a couple of pics of their lips. I just noticed today when I got home.

No, no experience with the lips thing. Don't know where is that coming from. I would add salt as a helper for healing/ prevent infection. I would expect it to go away under good conditions. Good luck!
