Gourami & Molly fighting - What to do?

[jkoven1]

hello,

i'm a complete newbie to this so bear with me...

i bought a small 1 gallon fresh water fish tank a few days ago. I decorated the tank with some gravel, a plant, and mini treasure chest. i added a male dwarf gourami to the tank and let him get settled.

after 2 full days in the tank i added a dalmatian molly. right away the gourami started chasing the smaller molly and became aggressive. the molly seemed quite frightened but was never in much danger b/c the molly is much faster and both fish generally stayed away from one another.

the next day (today) i woke up to find the molly now attacking the gourami by nipping at his back fin. the gourami is pacing while the molly has become aggressive. im not sure of the gender of the molly

does anyone have any ideas? should i let this continue or remove a fish? if so, which fish?

thanks
