So I have a 1,000 gallon goldfish pond with about 20 goldfish, one 6 inch pleco, one dojo loach, and 5 white cloud mountain minnos. I am trying to determine if I should get some snails to help clean up the pond. I know se are very prolific but I hear that trapdoor or apple snails are a good choice. I have lots of plants (lillies, iris, umbrella palm, anachas, ect.) And don't want the snails to eat all my foliage. Does anyone have a suggestion on snails from experience. What are my options if I choose not to put in snails. Thanks.
