Hi guys bit of a random question but can clownfish change sex? Iv had a pair of ocellaris clowns for about 8 months or so and they were both really small when i bought them. After a while i noticed one was slightly larger and seemed more aggressive which i thought ment it was turning into the female. That has been the case up until last night i noticed the male effectively  dive bombing the female who was staying in the bottom left corner and doing some weird shaking. There also doesn't seem to be as much of a size difference i don't think but the now more aggressive clown is still the smaller. Iv recently added another fish could that cause this? Or possibly because of the fact they havint matured they are still both males?

Hi, in a word, yes.  :glad:

Clownfish and other fish including some freshwater fish like most Cichlids  change gender. Clownfish form an order and a female will be the biggest and most dominant. If/when she dies, the next most dominant male will change and become female.

All the shaking and wiggling they do is all part of the bonding dances they do, psyching each other out and forming an order, or flirting...

So is it normal for the smaller fish to change behaviour and become the more dominant which appears to be happening?

Nope.  Normally it's the larger one that is the dominant one, and will become a female (and remain dominant).  However, it could be they're in the process of mating, as they do a lot of wiggling/dancing and other odd stuff then too.   :tongue-love:

There's also the possibility that is the female is sick, the male could be attacking her (mine literally battered the female to death when she showed signs of being sick - I pulled her out and put her in the sump, but it was too late).  Fingers crossed it's the top option! :s

I really hope its the first option however they are still small so id have thought they need to fully mature before they start mating. I could be wrong about them not being adults yet though

It's more about sexual maturity than size for breeding. Just like you get big and small people, but we're only capable of bearing children at a certain age, and as for how old they'll have to be, you'll struggle to get a definitive answer as fish will mature at different rates depending on nutrition, environment, etc again just like people.

Most recent additions to the tank have been a royal gramma. Mexican turbo snail and orange lip conch maybe they introduced something?   :|

 :O No feel for you- some will say quarantine tank but I suspect like (me for instance) we don't user a quarantine tank for what ever reason and thus pay the price .. some would say Oh its only a fish but hey that's like saying Oh its only a dog/cat either way you spend time and not to mention considerable cash in keeping them alive and happy only for them to pop there clogs ...

I suspect you will be keeping an even closer eye out now over the next few days to see if any one else is looking a bit flakey.. hope things turn out well for you

Thanks:

It was probably bullied to death like HK suggested. I wouldn't worry about the other fish.
