My fish are disappearing?

[Mike]

Hey I have a big fish tank in my house, mostly those little ones not bigger than half a foot but recently my friend gave me a new fish for a present and now some of my fish are disappearing. I'm worried and especially about the new fish my friend gave me because I dont want to lose it and have it look like i got rid of it
no little brother, my fish have been fine up until now and my friend gave me the fish a week or two ago
i have mostly clown fish and a few goldfish. idk what the one my friend gave me is, im gonna put it in a different bowl and see what happens

I think it ate it?

some fish eat other fish, maybe you should find out what kinda fish you put in there
