I just ran water tests on both tanks and they are identical. I am thinking on trying the blue tang in there now and see how the yellow reacts. If he bullies the blue I can remove him them. I have alot of room in the back of my rockwork and I just know the yellow is gonna be a nightmare to catch. Will probably have to break at least half the tank down to get to him.
I'm also concerned about the reson for the goby dying. I did find him in the pistol shrimps hole but I find it hard to believe he could have killed such a large fish. The pistol was about 2 inches when I put him in a few months ago so who knows how big he is now.
OR should I put the yellow in the 55g with the blue and see how they do?
I'm by no means lazy but I;d like to make this easy as possible.
