The red-tailed silverside, or zona (''Bedotia geayi'') is a species of
Madagascar rainbowfish endemic to the
Mananjary River drainage in
Madagascar. It is threatened by
habitat loss and
introduced species.
It has often been confused with the related ''
B. madagascariensis'', which is common in the aquarium trade.
