Watchman gobies

[goodtimes2]

I know you are not suppose to add two watchman gobies in a tank, but
how big of a risk is it for a spotted /pink watchman goby and a yellow watchman goby to be added to a 90 gallon tank. The pink/ spotted goby is already in my reef tank and a friend has offered to give me his yellow watchman which is a bit smaller if I want it. I have a Coral beauty, two clowns, in my tank with the current pink/spotted goby now.

I hae heard that pink spotted watchmen are some of the most aggressie you can get. If I were going to add 2 shrimp gobies to a tank I would do a red tsripe highfin and a yashia haze.

You may end up with major territory disputes especially if the new goby is smaller. I have a very large yellow watchman in my 65 and its very aggressive towards all the other fish that swim down towards its hole. I think if they were the same size and were added at the same time it would be better.
