Add a second clown?

[Mako72]

Hello, I am setting up a 29 Gal. Bio-cube...will move Ocellaris clownfish into that tank...could I add a second Ocellaris clownfish...is there a significant chance they would fight and be stressed? Better to keep it alone?

it should be ok. if you add another one though, get a smaller one.

I agree with patriots81 in that it must be a small one.

Clownfish are protandrous hermaphrodites. They are hatched as sexually immature fish. Based on signals from their environment they become physically mature after 12-24 months. They will either remain sexually immature, change into a male or change into a male then female. This is a one way trip, sexless to male never to be sexless again and male to female never to be male again. A clownfish kept by its self will become a female in a short period of time if it is physically mature, in as little as a month. I reccomend a small 1" or less size clown that has not been in a tank by itself for a long period of time.

As the two establish their relationship there will be some small battles but it should not end in locked jaws. If it does then you have two females.
