Although the water levels have not changed, there are signs of the water cycle taking place as there is condensation happing towards the top of the bottle where the grass is. The top of the bottle is foggy and has water droplets against the sides. The grass had grown just a bit since last week as it now touch’s the top of the bottle and some blades are bent. Concerning the water there’s seems to be no algae or anything; it looks perfectly clean and our fish seems to be healthy and alive.
