The H. fasciatus have doubled in size since acquiring them. A few comments thus far on this species, yes they are as aggressive as their reputation. I have lost one due to intraspecific aggression and intolerance of each other. So, I have decided to raise them separately and will introduce them to each other at a later time. Interesting observation about fin damage, this species constantly nips at the caudal fins of other fish. In addition one of the H. fasciatus had a large bit taken out of its dorsal fin (note the front of the dorsal - see picture) ; however, after a few weeks in isolation the dorsal fin has completely regenerated with no sign of damage.
