Hi, I have a Sailfin Tang that is about 3 to 4 inches in a 55 gallon tank. It is doing really good, but it's picking on my mono fish a little bit which is about 3 inches. I always hear that Tangs are aggressive towards their own species or fish that look like it so I suppose that is why. One Tang constantly picking on another fish was said to lead to death. I read that you should keep 1 or 3 Tangs because the most aggressive Tang will divide bullying between the 2 others and they will be fine. Does anyone think a Yellow Tang would be OK to add? I think they are beautiful fish and a have always wanted one. If not a Yellow Tang maybe other suggestions? I have hiding places and a good amount of swimming room. I know that they can and will grow and if I have to I will give them to stores or somewhere to let them live longer healthier lives (I really care about the fish). Other than the Sailfin and Mono my other fish are relatively small but can defend themselves. Such as Lemon Damsel, White Jewel, and Firefish Goby. Please reply soon, I appreciate your time, and thank you!
