Dreagonet male?

[Natalya]

Hi,
I've got Ocellated dragonet (brown) since last autumn ( so far I thought this is female !) ( video with her: http://www.youtube.com/watch?v=gRbONNycA4w) .

Now I try to find second another dragonet (red) for s/he .
I see that I don't understand sex differences of it!

I can find it for Synchiropus splendidus (green mandarin) in the internet. But I couldn't find it for dragonet!
Now I suspect that I try to make couple two dragonet males.... :hmm2:

Could you help me, please?
How I can define gender of dragonet?

for scooters, males have the big top fin, the female does not. you don't want two males.

Thank you very much for your replies!
Alas! I've got male-dragonet ! Since now I'll try to find femail-dragonet...
At first they (male+male) were living during 1 month +1 week. They were enough friendly to each other untill young male started to sleep next old dragonet each evening... I was happy: "hurray, what a sweet couple!" But Big Dragonet killed Small Dragonet soon . More precisely, the Big Dragonet scared the Small Dragonet to death)... Small Dragonet stopped to eating at all and he passed soon...

a male can also bully a female to death too. be prepared to have to separate them.

Peasofme, thanks! I'll bear in mind!
It never ceases to amaze me when fish behave as people ... Not only "If male met female they will be a couple". Love, hatred, friendship are present in fish world, too, indeed...
