i ordered some American flag fish to help with the algae in my pond. I was wondering if these fish would be ok to put into my water garden area as well where I house my pond plants for cultivation and growth. Will they eat my plants? Also will they be eaten by the other fish in my pond? I recently tried to put some Gourami in my pond and they were quickly devoured by my koi and catfish. I couldn’t believe my koi would do that but I watched it happen. The catfish didn’t surprise me but I was hoping for the best and very disappointed with the result. And the Gourami wouldn’t stay in the garden area :/ I definitely don’t want the same fate for my flag fish since I spent a good amount of money ordering them. Also any other info and personal experiences when it comes to pond keeping of the American flag fish would be greatly appreciated. My pond is around 4000 gallons. Attached is a pic of the plants I have that they would be around. Parrots feather, anacharis, mosaic, Ludwigia, creeping Jenny, aquatic mint, iris, four leaf clover, some others I can’t remember.
