I have two problems in my 40 gallon tank:
(1) My male gourami has been attacking the female and she has a white mark on her front like a white scratch, I saw him chasing her. What should I do?? I don't have a hospital tank, can I put her in the breeding cage or breeder?
here are some pics of the attcked female gourami.
(2) My other big problem reagards my male swordtail, he has been in my tank for about 10days now and 2 nighs ago my father accidentally turned off my heater and filter

, the morning after I found that the temperature had went down from 27C to 21C, and I also found my male sword tail lying on the gravel, but not dead. While the female is ok, he is now acting weardly. He went up to the top of the tank and is now constantly swimming against the filter's water stream without changing location, just moving his head and tail. When I feed them he just eats some few flakes and goes up again swimming against the water stream. occasionally he swims to the bottom or circles the aquarium, but still returns swimming at the top. Can anyone tell me what is happenning and what can I do please

thanks verymuch
