well the whpfins and tonos are knwon to be one of the more aggressive fairys out there i know first hand...but if you are looking for a red fairy the longfins are nice... i like the joanallene better than the rubriventralis but they are harder to find..the conde's are nice and i have always liked the very cheap rubripinis...the ones coming out of Sulawesi are very nice...bright blue throats..i see those go for 20-30 bucks and very bright plus they hold thier colors very well
