more than one fire goby

i have a firegoby in my 55 reef and in would like either one more of those or the purple one. will they get along? i saw on youtube somebody had two swimming together. anyone with experience? other fish in my tank are yellow tail damsel and 2 clowns.

 

would not recommend mixing red and purple firefish, when i did that they fought. I do have 3 red firefish that swim in a school but they were introduced together so im not sure about adding one later.

 

You could give it a shot if you have lots of hiding holes. I have seen both colors in small tanks but I think they were introduced at the same time.

 

i have a red and a purple, added about 3 weeks apart. they get along great. the pretty much have the tank divided in half but when one wonders across to the others side they dont seem to even notice each other.

 

I had three red firefish, all purchased at the same time. One ended up killing the other two. My tank is a 120g with about 60lbs of live rock. These fish don't school, but it may be possible to keep a mated pair.

I also started with three bar gobies. Two ended up becoming a mated pair and ganged up on the third, killing him off. Now the two live happily together.

I'd recommend keeping different species of gobies either singly or in mated pairs.

I keep:

1 firefish goby
2 bar gobies
1 scissortail goby
1 yellow watchman goby
1 yellow clown goby

All of these get along harmoniously.
