brackish to saltwater fish

[Danyal]

??? far as i know there's only one species and fishbase lists them as going between freshwater, brackish water and saltwater.

I went back to the site I read it and it talked of how their are 6 species in the genus Stigmatogobius and sometimes 2 of them are confused as knight gobies in the aquarium trade, 1 of which can go to saltwater. I guess this is where I read a 'knight goby' or a commonly mistaken knight goby, can go salt

idk, this one looked like the common knight goby, it was a male, about 31/2~4" long and i had him for over 4yrs before he jumped.

Maybe he jumped because he didn't like living in SW.

i think it was more likely because the tank was rimless and had absolutely no cover and either he was chasing the YTBD or perhaps one of the guppies
