Yes, mudskippers are not commercially available, at least when it comes to live ones. flashout, are you willing to sell your mudskippers?

Before Penang Bridge was built in 1985, I used to frequent the seaside along Gelugor watching the antics of the mudskippers along the mud banks. I had seen large males threatening one another, with open gills and their dorsal fins sticking up. I attempted to scoop them up with my net, but only managed to retrieve dead leaves and mud.
