Tomato clown fish

[Red Sea reefer]

So today I found I very nice tomato clown fish , I was planning to buy him but I had 2 Clarkii clown fish and one maroon clown fish and all of them are the same size with the tomato clown , what you guys think ?? I think it's too risky to add him to my 190 gallon tank

I think you would end up with fish chowder. Unless your maroon has established at the opposite end of the tank from the clarkiis, you may already have a situation developing. The only thing that is likely keeping the equilibrium is that you have one mated pair likely anchored by territory, and the other free-ranging. Two mated pairs in that distance, each well able to claim 50 gallons or more---I do not see it ending well.

Yes the maroon is in the other side of the tank , for the last year the tank same to be peaceful

All 3 of those clowns have nasty attitudes when they mature and like Sk8r said it's not going to end well. I'd be surprised if you have more than one alive in the next year.

I'll wish you well and hopefully some way some how they all learn to live together.
