Hello, I posted this question within another post and felt that it might be better asked outside the post as a new topic. Hopefully I'll get some more detailed answers...
Is it necessary to have to have some sort of pump or (electrical) filter in a pond if only water lilies and aquatic plants are in the pond? Or, are water lilies like lotus plants and can just grow in a tub without any sort of pump device?
What changes if I want to add maybe 1 or 2 small goldfish to eat the mosqitoes and constant toad eggs being laid in my pond/tubs? I have learned that the toadpoles devoured my newly aquired anacharis plants.
Don't know if they would also try to eat any newly formed lily leaflets. Maybe someone can tell me.
