@KarenLR75 - I wouldn't say you can't do what you desire. Nor would I say just because you see it on youtube means it is possible either. What I do know though is this. Based on the image you posted above (nice tank btw and frame) you have the room and gallons. What is missing is the maturity of the tank and cover. Meaning tangs graze, they swim, and some have territories. Unless that is an earlier image you don't have that yet. Do some searches in the large tank subforum - O2's tank comes to mind of a lot of fish in a mature tank. Good example. Others members such as @Dmorty217 provided good information.
Don't throw caution into the wind and you should be fine.
Hey saf1, just to clarify, I'm not the one with the 500 gallon tank who started this thread. I wanted to acknowledge the beauty I can see in her future tank and do what I could to help her first time posting on the boards and not knowing there were other forums...to be a more positive (AND educational) experience.
Since she's had multiple tangs that are being held in her 75 gallon QT tank and has mentioned there are other tanks in her house, I could be wrong but she doesn't strike me as 'new' to the hobby. She shared she ended up in the 'New to the Hobby' forum without realizing there were other forums where she could have posted the question.
On her list of other tangs she hopes to acquire at some point, I mainly wanting to open up the possibility of maybe reconsidering the types of tangs and not getting caught up in the specific number tied to a specific tang as I am NO tang expert plus I can only DREAM of having a 500 gallon tank..lol..but was hoping those with experience with multiple varieties may be able to weigh in with some 'alternates' to consider if a specific clown is more crazy aggressive than any of the rest.
I'm thinking you got us confused as I only have a 112 gallon tank (6 ft long) and we have only 1 tang - a white tail bristletooth tang and after consulting with others and our LFS, he is going to be our 'showpiece' fish so in OUR situation, we are not going to introduce another tang into the mix (had considered a yellow).
Other than the tang we have 1 blue throat trigger, a mated pair of percula clowns, a piggy melanarus wrasse, a Randall's Goby & his shrimp, 1 green mandarin, and 3 fire fish. We also have a mixed reef tank (not fish only).
Our biggest thing we wrestle with is whether to do a small school of chromis and/or anthias. Just want to clarify who I was so I don't take away from OP's thread.
