Please forgive me for sounding like a jerk with how I explain things. If a clown is similar in size it will hold it's own. I'm not saying to part with a fish that brings you joy as that what this hobby is all about. It can be very rewarding if you master the simple things. I think everyone here including me has learned fish don't always get along. I had lion fish that should have ate the fish they were living with but they didn't. I've introduced fish at the same time to minimize fighting between fish that usually dominate a tank. I think the only way to learn who gets along with who is trail and error and great advice from members of this forum that have owned a specific species. What your doing is a great practice to get into in regards to asking what you do not know on this forum. There is a wealth of knowledge here and nobody wants to see an animal suffer for no reason. My biggest mistake in 40+ years reefing was using dry ice in a sump once during a heat wave

. I almost killed every fish in the tank in one fell swoop. I now ask advice and discern what applies to my situation at the moment......Now , does anyone know about external clutches on my S&S Harley that I screwed up today, LOL!
