This species inhabits mud banks which are covered by such vegetation as mangroves, nypah palms where the water is of very low salinity, near 0 ppt, in the upper reaches of estuaries and in small tributaries.[3] It can grow to a length of 10 centimetres (3.9 in) TL.

This species is of no interest to local commercial fisheries.[2] The specific name means "seven rayed" and refers to the seven short rays in this fish's first dorsal fin.[4]

P. septemradiatus is the only fish known to communicate acoustically while out of water and when they are alarmed they dash towards land rather than water.[3]
