I'm planning on implementing a small pond to attract insect-eating wildlife (especially frogs and geckos) to my garden to reduce the population of mosquitoes and gnats. After planting my food forest I don't have too much space left, I'd dedicate at most 2m² for it.
My main questions are: is it even feasible to have such a small functional pond? How can I passively aerate the water (are there underwater plants that excel at it)? Also, I live in an area with incidence of dengue, so it's important to have some fish that eats the mosquito larvae. Which fish would live well in such a small environment, eat the larvae, but also eventually some plant matter (so I don't have to buy fodder in the winter)?
I'm sure I'll have more questions afterwards, but so far those are the most important. Thanks.
