Spawn in tightly bound clumps in freshwater pond on open grassland.
No interactions present.
I noticed a cat taking an interest in the pond in our back garden this morning. When I went out to investigate I saw around half a dozen splashes from frogs diving out of sight. The spawn in your pond is early but frog activity in our pond suggests that you do inded have frog spawn already.
