I currently have a small powder blue tang but 2 days ago I added a smaller blue hippo tang and my powder blue tang chased it until the hippo has to hide in the rock. I was able to take the small hippo out.

However, I just bought a medium size blue hippo and want to have a second try. Do you think that a bigger size hippo that is larger than the powder blue get go inside the tank? My tank is 75 Gallon but it has hiding spots.

How should I add this hippo tang?
