That's very cool! What have you got them feeding on?
I think these are P. barbarus? More photos would help with this, but also seeing more pics of these animals is just a treat anyway.
You just got them today
Have not tried feeding them yet
And yes it is Periophthalmus barbarus
Was worth getting as it is a hard to find fish
And is very cool
I tried to get a male and female but the guy and me did not know how to sex them.
And thank you

Were they really hard to find? I've been out of the game for a little while, but a few years ago, at least P. barbarus popped up every now and then. I guess it is a really specialised fish to keep, and not many people have the facilities to house them.
The male/female thing can be a little tricky to determine. In my case, I found out the hard way - in that I believe I had two males, where the larger one would absolutely not tolerate the smaller one. I was fortunate in having a massive setup for them, so they didn't cross paths often. Even so, males will harass females, making this behaviour difficult to judge. The larger one developed strong colouration every so often - this happened rarely for the smaller one.
I've found they adapt well to frozen foods, but never got them on to dry foods. Live food, such as crickets, flies, and worms, are good treats.
Is that tank covered? If not, quick tip - do it. This serves to keep your pets in (as they're pretty great climbers), as well as keep the humidity up. Humidity is important for when they're out of the water.
Again, all the best. They're great wet pets.
