how small is too small?

[Ballyhoo]

I just picked up a new male clownfish from marine soultions to pair with Penny my female. He's about an inch long and she's about 3 inches. Should I let the little fella grow out a bit before I introduce them?

The tank is a 40 breeder with 50lbs of LR the only inhabitants are penny and a six line named hush

What type of clown, do you have anem or anems?

[Shep]

it's been my experience that as long as they are the same kind of clown it won't be a problem...

I feel it's better to introduce him now rather than later, however keep a watchful eye on aggression.  If she beats him up to bad you may need to separate them, let him heal up and then reintroduce them.  This happened with my pair of Picasso's, she completely chewed off his tail which has thankfully regrown,  and now they are best buds.  Just keep a eye on them and they'll be ok.
