I did a quick search on "clown compatibility to see what the issues are with clowns in general. When they are the only one in the tank, they don't really bother the others unless they try to enter their territory. Clowns tend to be an aggressive fish, and since he's been in your tank 1st, he's most likely going to be the aggressor between the two. The bigger the tank, the better chance of them living cohesively as it offers more room to get away from the other fish if they fight and one needs to flee! Attempts to pair them has a higher failure rate than success. From what I read, most experts are saying that it's not a good idea to mix them, because more times than not, it just doesn't work out. The search I did was on "Clown compatibility", and I found a particular page that really pertains to your questions. Since there are many examples of pairing being attempted, you might want to peek at that page and see all the pros & con's to make your decision!take a look at:: http://www.wetwebmedia.com/clncompfaqs.htm
My concern for you would be giving it a try, and then having it not work out well.
Gold Stripped Maroons tend to be the winner of who stays and who goes.

If you decide you want to try it though, make sure the clown you choose is at least the same size or a bit bigger than your Gold Stripped Maroon. Be sure there are several great hiding places for the less aggressive one to run to if necessary. If you have another tank one can be put in if it doesn't work, that may be a solution for you. If your Gold Striped Maroon has it's own anemone that it hosts, don't expect that it will be shared with a newbie. You'll have to get him his own "lovey" to snuggle in. I know from experience that the 2 maroon clowns "a mated pair at that" we had, gave each other a run for their money. I finally had to find them a new home as I couldn't handle being bit by them anymore. They were always protecting their territory, and if you get close...watch out, and we all know that we do have to stick out hands in there when needed. I would come out with bloody little holes in my skin, and their bites left little scars on my hands. We gave them to another member that had a tank just for the two of them, and that turned out to be the best for them and us as well!

Listen to what others suggest as well because they may differ from my experience & reading. I'm by no means an authority on this! :reading: Stranger things have happened. They could get a long just fine, have a little marriage ceremony at the live rock alter, and make babies like crazy that are rare or something...hopefully making you rich!! This ones up to you! Sorry I couldn't be more upbeat about them. It could be this #*!@$%*# :smt075 #*!@$%*# or this: :smt049 :smt054 :lovestory: :smt049 :smt050 Good luck to you on whatever you decide. .....Angel :angel1:
