I am just happy to know there is another Brook Trout pond on the forum!! If you stock more rainbows there will be even less food to go around for the Brookies. 21" Brookies are a BIG deal. Not many people will EVER catch a 21" Brook Trout. I do not know any trout person that would want to mess that up with Rainbows, especially stocker Rainbows. Why not stock some fathead minnows and add some structure for them to hide/spawn in?? That would feed the Brookies instead of compete with them for food. I've had fatheads in my pond for over a decade. If crayfish somehow migrated into your pond they would eat the weeds AND feed the Brookies.

If you are new to pond ownership I would recommend NOT running out and making changes too fast. Read up on this forum. Study. Ask questions. Then you can make a well informed decision that doesn't backfire on you.
