This weekend I had to emergency rescue three goldfish and they got put in my 10 gal, so the two boys in there had to be put somewhere else. I don't have enough heaters so I put one in my other boy's 3gal tank with a divider until I can get something else worked out.
Last night they got past the divider while I was out but when I came home no one was even nipped. They were just sitting, near each other I might add, and not even flaring. Neither has any injuries and while one male has lost some color (don't blame him) they seem perfectly fine; ate well and acted normal when I came up to the tank.
I tried to fix the divider and make it fish proof, but they got into each other's tanks again, and again nothing happened and there were no injuries. I went ahead and took the extra boy out and put him in a cup because I don't want to press my luck but I'm still confused.
Can males tolerate a certain amount of time together before they flip? I spent the night at a friend's house and didn't get back until noon so they could of easily been in each others side for a few hours.
I am NOT going to experiment and see how it goes but I was curious if anyone else had an experience like this?
Thanks for any comments. :)
