It’s not easy for most people or other “regular” fish keepers to understand why we maintain this type of collection and spare no expense on this fascinating hobby.
This is why the that waters of the lower balsas rivers cannot be expected to be very clear, so that only in the headwaters of smaller affluents is there visibility in the dry season.
