丝尾凹尾塘鳢（学名：Ptereleotris hanae），又名丝尾鳍塘鳢，为凹尾塘鳢科鳍塘鳢属下的一个种。

Ptereleotris hanae, the Blue hana goby, is a species of dartfish native to the western Pacific Ocean. It is a reef inhabitant, being found at depths of from 3 to 50 metres (9.8 to 164.0 ft), though usually no shallower than 6 metres (20 ft). It inhabits burrows made by alpheid shrimp, but unlike the Amblyeleotris gobies who normally associate with these shrimp, this species has no interactions with their shrimp hosts. This species can reach a length of 12 centimetres (4.7 in) TL. It can also be found in the aquarium trade.
