Do you think it will be hard to find a pet store that will take the fry? My brother wants a couple, but after that I'm not sure what to do with them. The older ones are ready to go, I'm just waiting for my brother to pick a couple up.
There's always some bad with the good. Besides, a little critism is always good. Marsdin is right. All that really matters in the long run is that they are healthy and happy. My family and I like the marbles in the tank. It is different than what most people do with their tanks. The pictures don't do justice to what they actually look like in there. They give it a sparkle.
