I don’t think I have any red ear sun fish but I will definitely look into putting some in.
Let's correctly identify the grub first. I am NOT an expert on parasites - but we do have some actual experts on the forum.
If red-ear sunfish will be a big benefit for your situation, then you should probably read a few of the threads in the archives. For an existing pond, you will have to stock the proper size and amount, so they are not just expensive snacks for your existing fish.
