Although I can raise Rams to 1 inch or more in 8 weeks, I cannot achieve the same rate of growth with apistos. Cacatuoides are relatively rapid in growth and might exceed the one inch in five months. A. bitaeniata on the other hand seems to grow ridiculously slow once they reach about 1/2 inch in length even with ample room (one gallon per fish) and the best foods (primarily live foods). A. borellii grow relatively quickly as do A. agassizii. I have several other species that seem to follow the bitaeniata model.
