The assumed "eggs" are clear around the edges and more opaque in the center,with a singular single black dot. They are individual not in a clump and randomly spaced on the front glass of the aquarium. They are not circular more bean shaped and approximately 1 1/2 16ths of an inch to slightly less than 1 16th of an inch.
Current inhabitant of the tank are danios, cory cats and a gourami, many plants and no snails. Tank has been running 6 months before sightings of "eggs" no new additions of plants or fish in about 2 months. Plants an ornaments have been sterilized prior to addition to tank with a 20/1 solution water/bleach. Please help!
