Well, by looking at the pics, I have both b-gill and greenies.. The greenies dont seem to have as much of the blue in them on their side though.. The fish I have have a small mouth big enough for a jig and thats about it.some of the bigger ones are close in size to the mouth on a 8in.crappie. By yellow belly, it seems the ones that are full of eggs are the ones with semiyellow bellies.. They arent as pure yellow as the specimens I seen in the pics.. Reckon I have some good inbreeding going on in my little pond? The cats are growing by leaps and bounds but I need to get some shellcrackers..What are they gonna do to what I have?
