At 1-1 1/2 inches, your boesemani are probably 3-6 months old. They will slowly and gradually color-up over the next 2 years, although if you have female boesemanis, they will not look anything like Gregg's male boesemani. Also, Gregg can correct me if I'm wrong, but it looks like he got the 10 pack of male rainbows from Tanner on aquabid (rarefishatlax), who has some of the best-looking rainbows available in the US. Only a very small percentage of the male boesemanis sold in local fish stores will have the intense orange of the fish that Tanner sells.i have 2 boesmani rainbows and they have almost no color... they are about 1-1 1/2 inchs in length (how old do you think they are) and how long will it take for them to color?

Here is a list of the type of Rainbows in the pics. They are in the order of the original post.
Tami River, Millenium Rainbow (Glossolepis Pseudoincisus)
Blue Rainbow, Lake Kutubu (Melanotaenia Lacustris)
Boesemani Rainbow (Melanotaenia Boesemani)
Running Creek Banded Rainbow (Melanotaenia trifasciata)
Goyder River Banded Rainbow (Melanotaenia trifasciata)
I have found all species of Rainbows to be very compatible together. I have other species also but haven't been able to get any decent pictures. I'll add to the post if I can get some.
My fish started coloring up at around 4 months, but really started showing nicely at about 7 or 8 months. I should also note that my tank is all males.
Here is a full tank shot, and another member of the commumity: The Roseline Shark, Denison Barb (Puntius denisonii)
Your tank is one of the reasons I am currently setting up my new 75 gallon as a rainbow tank.![]()
