Aside from the tadpoles and fish there are two water beetles, a couple free swimming insect larvae too big to be eaten, and one huge larva, idk what he is, he's great though. Spends most of the time on the underside of a submerged leaf, occasionally comes to the surface for air but it's funny how he does it, how he swims, he's always on his back looking up at the surface with two big legs propelling him through the water, when he comes up for air he walks along the underside of the water's surface with his four little legs, submerged the entire time. He takes a quick breath before quickly swimming back down. I'm wondering if he'll eat a minnow.
I planted a couple water lily bulbs in the substrate so in about a month and a half should have some real plants on the surface to replace the island of leaves. There's some emergent non-aquatic plants planted into the substrate but they'll probably be dead soon.
