Well the bgk is 12-13 inches. As far as the bamboo shrimp go.....what I can tell you is they died. I don't believe the bgk had a part, my bamboo shrimp were 3-4 incheslong. I've been contemplating tossing in a few Amanos to see how they do but I'm worried my geophagus may be the culprit.
The congos I bought from my Lfs and they are pretty much always that size when they have them. I bought them a year ago do I'm sure they may have grown a little. How big is bichir?
