Biocube stocking question
I recently picked up an established 29 gallon biocube and was wonder on if I could maybe add a couple more fish to it.
It currently has 2 clown loaches , a blenny and a gobi as well as 4 or 5 hermit crabs and 4 or 5 snails. Is there enough room to add a couple more fish? I would really like to put a couple yellow tangs if I was able to do so.
This is my first saltwater tank so I don't want to screw things up if I can avoid it. Thanks for the help.
