Frog eggs and cane toad eggs have distinct differences that can help in their identification.Frog eggs are typically laid in clumps or spreading mats, often attached to rocks or vegetation underwater, or as foam on the water's surface.In contrast, cane toad eggs are laid in long, continuous strands of clear jelly, resembling small black pearls in a long clear tube, and can often get tangled in underwater vegetation.
Toads can't climb smooth surfaces so any eggs in a glass fish tank will be frogs.
Use hygiene: Do not leave uneaten dog food around and keep the bird bath above ground.
