There are some sedentary Pikes such as C. jegui that spend most of their time waiting for prey to swim by, at which time they lunge and grab the hapless fish. Predatory fish vary in their level of activity. To compare with saltwater fish, Pikes are somewhere between Rockfish and Barracuda in style and activity. Most Pikes position themselves near sunken tree stems, rocks and substrate, giving a quick, short but spirited chase to catch prey. Keeping Pikes in aquaria requires that you remember this fact.
Pikes come in many sizes.
There are manwy dwarf Pikes that don't grow longer than 3-4 inches. They possess most of the color and interesting behavior of their larger cousins but remain small enough for aquarists to enjoy without giving up much floor space for fish tanks. Then, there are many medium-sized Pikes that reach a maximum size between 6 and 10 inches. And finally, there are lunkers, growing to 18-24 inches. There is a Pike for everyone.
