Hey guys! So ever since I first saw one many years ago in my favorite aquarium book (Encyclopedia of Aquarium and Pond Fish by David Alderton) I have adored the rosy barb. I did briefly have one about 14 years ago and it was a reddish one but the ones I'm currently seeing at my local Petco are sort of a golden brown, probably young ones I would imagine. I think the golden brown ones are very beautiful but I'm planning on putting two of them in the tank I'm in the process of building (only two since apparently they grow to 6 inches) and I'm really hoping for the copper red coloration. I heard only males develop reddish coloration. Is that true or do they all turn reddish eventually? None of the ones at the store right now are really showing any hints of color so if only males get red is there a way to identify a male or a female at a younger age? I was assuming the slimmer bodied ones were in all likelihood males and the rounder bodied ones females.
