Hi
It would help, if you let us know what kind of fish they are?

 

I'm really sorry that I disn't give much info on my fish but I have no idea what kind of fish they are,one is white with orange on him and the other is brown,,I think that they are the same fish though,,they look the same,lol,is there anywhere that I can put a pic of them on here to show you

 

you can post a pic on this page. go to modify in the right hand corner of your first message. when your editing your message go down to additional options and click

 

this happens to me too!
It is for all kinds of fish!
