I bought a new GBR and not sure if it is male or female.
I currently have a female in the tank. Both were bought from the same store. I bought one Thursday, then had non-buyer's regret and went back to buy the other on Friday. When the new fish joined the female in the tank, she acted very excited and put on a display as if they were previously a mated pair and had been re-united. However, now that "he" has colored up, "he" has a pink tint. As for the fins, its hard to tell but they often look rounded and not pointed. What do you guys think? Here's the best picture I could get of the fish before I added to the tank.
