I like how you added no fish "that you no of" it made me laugh a little because I'm the same way. I always end up with more baby fish than i thought. I feel like no matter how many plants or what type your pond will do way bettter. But i have heard of people who don't want any plants and there ponds and fish are great. I feel like having half plant cover makes the pond look more realistic. But also, some people are in it just for the fish.
