Are there any live plants or tank mates in your aquarium? If so, what species?
Java fern, java moss, banana plant, 5 anubias (various species), duckweed (so much), and hygrophila corymbosa var. angustifolia. Had a mystery snail named Cargot (short for Escargot) but he chomped all my plants so I moved him to a tank at work.
Details About The Aquarium
Tank is a WalMart brand kit – came with tank, internal filter and pad, and a hood/light. Switched out the filter for a sponge filter, added a 25w Cobalt NeoTherm heater, and swapped out the hood/light for a 16w Stingray and an acrylic lid.
