Fish was added to my tank newly recently.
Those seem to come from Taiwan.
It's also distributed over the Japanese most south. But it's rare to reach Japan.
It's fish of a goby family, but an English name is Loache Goby.
It's similar to Homaloptera for certain.
A Japanese name is TSUBASAHAZE and the meaning is wing goby.
They have no suckers.
However, they can fix a body on a rock in the rapids.
They make down force occur from a watercourse by the big pectoral. They seem to fix a body on a rock with that.
A blood worm is a favorite for them.
Somehow they don't seem to do alga grazing.
Formosania lacustre is one kind of HillStreamLoach which lives in Taiwan likewise.
