Hello everyone-
I have a 20 gallon reef tank that contains 30 pounds of LR, 10 hermit crabs, 1 turbo snail, 1 cleaner shrimp, 1 percula clown, and some green star polyps (only coral for now, its a relatively new tank). All my levels are fine (0 ammonia, 0 nitrate, 8.2pH, 1.024 sp gravity), and I would like to add a few more fish to the tank, and I have 2 questions about that:
1) can different species of goby get along? I was hoping to add a green clown goby and a firefish, and possibly a yellow watchman too, which brings me to my next question,
2) if I had 4 fish total in the tank (the three different gobys listed above and the perc) am i overstocking my tank? i wasn't planning on adding anymore invertebrates except coral.
any help would be great. thanks.
