When to Stock.
After the water has stood for three or four days, and the aquatic plants have started to grow in their new quarters, you can stock the pond with sunfish, rock-bass, dace, small catfish, crawfish, carp, and goldfish. The two last-named are the most stupid of the fish, and the rock-bass is one of the most intelligent fish I have ever kept in captivity.
