Crenicichla johanna and Crenicichla sp venezuela (strigatas haven't been exported since mid 2000s) are not smaller pikes like compressiceps. If anything they are part of the lugubris family and easily reach 12", even for females. They are far from being placid. Raising from these from juveniles guarantees nothing.
Most pikes are best left with soft water as opposed to the Central American cichlids like vieja types and convict types, which thrive in hard water. The lugubris family get HITH within the first 5 years if kept in hard water.
