I bought 4 gouramis for my tank, and the shop owner told me 2 were males and 2 were females. soon 2 of them started "playing" with each other, what seemed like 'kissing' each other's sides.
Soon after the third one joined in. At that point I decided to check if there really were 2 males and 2 females in my tank. I did some research online and it turned out that only one of them was a male, and he was the only fish that did not participate in any "fighting".
He died the night before... :( having gone calm and refusing to eat for a day, then having lost balance and being unable to swim properly...
And the females are still fighting :S nothing serious like ripped fins, and they dont attack other fish, just the 3 of them messing around.
but they swim after/chase each other a lot and there seems to be some competition between them too when they eat worms.
Is it just being territorial, or were they fighting because there was only one male around?
