Our natural pond is starting its own ecosystem. Different lifeforms are coming to life in the pond. Even the mosquitofish have spawned lots of baby mosquito fish. The bottom of the pond is starting to turn green, as desired.
We have cockroach like insects crawling on the bottom of the pond. These are naiads that morph into dragonflies. They leave behind their empty skeletons around the pond.
Pursuing Wabi 
蚊の幼虫を食べるモスキートフィッシュ、モスキートフィッシュの稚魚をたぶん食べるヤゴ、そしてそれから産まれる小さい青いトンボ。。。これはだれが食べるのか？なんか、エサもやらないのにどんどん勝手に増殖するこのワビポンド（池）。ちょっと怖いぞ。
looking very nice!
you can see so much at the bottom. when its all green the little creatures will be much harder to spot.
so cool!
BEAUTIFUL, DID YOU LINE THE POND WITH A BUTYL LINER OR SIMILIAR OR IS IT JUST CONCRETE?
