How big is your engineer goby?

I've noticed this thing is getting big over the last few months. I guess I didn't do good research... Just noticed they get a foot long .. wow.
He's probably 6 inches now.

 

My son back in Va. rents my house there and I have a built in 125 upstairs and he was setting there one night called me in a panic and said POP!!! what did I just see it was black and yellow and about 2 ft long and about as round as a Hot dog LOL last I saw it it was like 18 maybe 20" Long he has to be about 11 yrs old now ? I put two in there as 1" little ones still looking like fish more then a snake I guess the other is still in there also ? I have heard it said they are like a foot long Max ??? So much for books and what they say maybe in the wild they stay at a little smaller ? But being tank fed and no predation they did not consider that ? .. But I have seen many over a ft long upwards of 16 to 20 "

 

When they get full grown and lose their juvenile coloration, they get "pit ugly" IMO too.

 

Wow.... that's huge.. any problems with him eating other fish and verts?

 

Hey Curt you have that right they look like a snake great sand and behind and around the rock cleaners though , But you best be sure the rock work os secure and solid or they will tear it down. Huuum maybe hence the name engineer goby's LOL And here I was thinking trains all this time LOL

Yes ! crustations are tops on the list they will take a small enough fish also I have never witnessed any fish myself , just heard about that. But I have seen them suck up many a shrimp and hermit's
