How many Gobbies can i have?

red reef · Aug 9, 2015

I have a 360 gal tank with a live sand bed but not a DSB Tank has been up for about 2 years now. I have 1 diamond back gobby now but stays mostly on one side of the tank. Can I safely add 1 or 2 more? and should I get a different kind?
All help is appreciated
Thank you

I have seen several I the same tank at lfs and they seemed to be ok together. In a tank that large you probally won't have any issues, however there is always that small chance.
I just did the same thing with some tangs I had in my frag tank, I added and atlantic blue,blue eye kole and another yellow to my 325, I have a 7" vlamingi,hippo,and a yellow in there already. I just over fed the tank dropped them in and turned the lights off. Hopefully they make it through the night.:(

LFS tanks are not a good baseline for what will work at home. Diamond gobies will pr up and prs are intolerant of conspecifics within their territory. Their territory is roughly between 2-3 ft squared, so a couple prs may coexist.

Pairing a single diamond goby with a new one is pretty simple, just get one as small as possible to add to the existing goby.
