Those are some beautiful angels you have. Your ramshorn snails look like your water is lacking a little calcium.

All matter is merely energy condensed to a slow vibration, we are all one consciousness experiencing itself subjectively, there is no such thing as death life is only a dream which is an imagination of ourselves. Bill Hicks
