Does anyone know much about them? I went to a bunch of different web sites but couldn't find out much. That might not even be their real name(you know how lfs are sometimes). Most gobys seem to be brakish but this one was in with freshwater and not in the brakish section. They are kinda neat fish but not sure of aggresivness or size.

Are you talking about mogurnda mogurnda? If so, that is the purple spotted sleeper goby, also called purple striped gudgeons. Is this the fish?

These guys can grow to about 6" in length and will be very thick like little sausages. They will eat anything that fits into their mouths so be careful what you house them with. I love mine. They are little characters. I have 3 and am hoping to have a mating pair within the group. You can teach them to hand feed. They are freshwater gobies.
 
This thread somehow caught my eye.

According to fishbase, all mogurnda species are freshwater. Most come from rivers and lakes in Australia and New Guinea. Completely not brackish.

The Goby you are talking about often has the common name "Marbled Goby" I'm not sure of the scientific name of them, but I can find out if you'd like. They are very interesting, but HORRIBLE for a community tank, first of all they can eat a fish almost half thier own size, and although they spend most of their time waiting for prey at the bottom of a tank, will often move at pretty incredible rates if startled. I'd say unless it is a showcase, or pet fish for yourself, stay away from them! There are plenty of other, more peace-loving gobies that suit a community quite well. They grow to about 6 inches in size, and come from the Malay Penninsula. Like most gobies are pretty fussy about having live food. They are very hardy fish as well, and can take nearly any tempature and pH range, (within reason)

Thanks for the replies. I guess the lfs spelled it modurnda.(According to anything I found out they may be related to mudskippers. They blend in great with sand and are about 1". Their heads and coloring are different than those in your pics Nippy. They just sit real still so they are probably the "marbled" that vato posted about. Oh well I'll get something else.

Thanks
 
The scientific name for the "marbled goby" is Oxyeleotris marmoratus or Oxyeleotris marmorata (depending on who you ask, so I'm not sure the true scientific name)
