Hi there!
I went to Lantau Island and took some of photos in August. Please help me to ID!
I think they are Periophthalmus modestus. But it's possibly to be P. argentilineatus as well.
They looks very common there.
And does P. argentilineatus exists in HK???





Thank you!

It should be P. modestus

As far as I know, no records of P. argentilineatus have been made in HK so far.

On the other hand, another species P. magnuspinnatus has been recently confirmed to occur here, though its local known distribution appears to be quite restricted to the northwest of HK.

You may refer to these below discussions (though some of these are in Cantonese):

Thank you for your reply Tommy.
That's really helpful tips. I followed your links and checked P. magnuspinnatus photos. They look much darker compared with P. modestus.
I think they were P. modestus too. Thank you.
