female siamese fighter fish are not as attractive as males, and can be kept together,
males are the aggressive ones, and much better to look at..
damo, chuck him on top of your dvd player/set top box/something similar, this will help keep
the water temp up, alternatively, grab a heat matt from a reptile store and sit him on that.
EDIT: alternatively, stop being a pussy, and get a real set up, African Cichlids ftw
