Picked up a female GBR from Petsmart about a month ago. They had them on sale for $5. All they had were females so I bought the one that was showing the best colors at the time. This past weekend I made the drive to 3 other LFS specifically to find a male GBR. Stike three!!!! So my last chance was Petsmart. They had one that looked awfully male, so I rolled the dice and picked it up. Not 100% sure it is a male, and the fish is not adult size yet, but so far its looking good. The new GBR and my female GBR are inseparable. Either way, they are both gorgeous and their colors are absolutely striking.
Well this was answered today. Noticed my GBR's were acting very territorial towards one of the back corners this morning. Looked closer and noticed they spawned on a temporary rock I have placed there to hold down my manzanita branch. I was surprised as I didn't think either was fully mature yet. I don't plan to attempt to keep, hatch and raise these. If a couple survive in the tank, great, but I don't expect that to happen. I may consider picking up a 10 gallon and sponge filter to try and raise a brood in the future.
If you look closely at the top of the rock and through the leaves, you will notice the eggs. The male has been spending much of his time guarding the spawn site. I think my Amano shrimp are on to him though. There are usually a couple hanging around acting very opportunistic.
