Welcome, Sam! Your grandson is adorable, and I'm sure your tanks are lookers, too. We'd love to see pictures!! *hint hint*
I think you'll find the forum is pretty active. I actually came here because of all the activity I saw. My last forum basically only had one or two member that posted anything.
I have to admit, I needed to look up most of the names of your fish because I'm not a cichlid person (all I really know is they are the African equivalent of centrarchids). But those are some pretty fish. I'm sure if we don't have them in our fish profiles, Byron would be more than happy to have you add them.
