All the haitiensis I've owned were killed by grammodes or argentea long before they made 5" but the festea survived so i'd say festea. but as stated I never owned a haitensis over 5" My festea were more stand offish they didn't really attack but didn't back down either.The haiteniensis got stressed when the other totally dominated them & would die later even after other fish were removed. Haties. have to be dominant or solo feteas are more tolerant As stated individuals will exhibit different levels of aggression.But on average hatiensis are seemingly more aggressive because if they are not ruler of the tank they die, festea can live on either side of the pecking order.Hatiensis are on a different level until something stands up to them then they run & never again regain their confidence at least not the 5 I tried.fishluvr12;3216280; said:I'd say the hait when they are under 10".But 10" or larger the festae.
