I have a 30 gallon tank with a Maroon Clownfish and a Sand Sifter, my girlfriend just surprized me with a Gold Stripe Maroon, my question is if I put the GSM in the 30 gallon with the regular Maroon is it possible they pair up or will they most likely fight???? They are both the same size and the Maroon has only been in my tank for about 2 or 3 days... Help please!!!!!
