hey! im new here and i have two bettas and my little sister has a goldfish. One of my bettas was looking bad so i put him in with the goldfish, which has a bigger tank. I know that Bettas work with some fish and a friend told me its ok to put them with goldfish. Also, i know that bettas can get aggresive with goldfish. I have been observing the two fish and i really noticed that the betta is chasing and terrozing the goldfish. He is actuall chasing the goldfish A LOT. Will this change? Is it ok? What damage does it do? Will the goldfish have a miserable life??? I feel bad. Honestly I want the best for them. Basically is it okey to let them "settle their differences" or should I interfere and seperate them? ??? Will it stress the goldfish tooo much or what?? PLEASE SOMEONE give me some advice!!!!! Thanks, Animal Luver!
