I just can't imagine in nature that after a drought/or drop in water levels, Crypts drop all the trerestral type leaves?
I have this idea for a type of tank that minics nature's wet & dry cycles. It would house Crypts & maybe Java fern, Labyrinth fish. During the summer months I would drop the water level. We don't air condition the house during the day when we are not at home but we do leave windows open/fans on. I'd have to think an emersed type tanl with a top would stay humid?
