This does not go for just Betta fish but any living, breathing animal.
The reason I wrote this, is because of someone and their two bearded dragons. A new baby beardie, and her older baby beardie who was twice the size. Despite people's great advice, the person says: "I'm just letting nature take it's course." That right there, set everyone off.
So if you hear someone mentioned "Mother Nature does that, why can't I?"
or allowing nature to take it's course
in something other than an elderly animal's peaceful passing, please mentioned this to them.
Mother Nature does things we frown upon in the practices of hobbies, and amongst hobbyists. Some think Mother Nature does things, that allow us to be absorbed in the ignorant bliss of sheer laziness. Letting "nature take it's course" without meaning the peaceful passing of an elderly animal, is WRONG. We have the skills, the brains, the emotional means to bring only greatness to our animal's lives. Please take a minute to read, you won't regret it.
We took away Mother Nature, when the first animals were captured. Over many years we have learned our mistakes, and come to realize with every passing day, every passing year, that WE are MOTHER NATURE. We became what we took away. We give them "sun", we give them "water", we supply their "food", we remove their "waste". Not in the same way Mother Nature does, but in the way we can, in order to keep them happy and health.
In the wild, the environment cares for itself. The soil absorbs, the plants release, the bugs produce - everything that the animal needs is right there. But even then, they pass away at an age almost always less than half of the age they can live in captivity.
We are the reason animals get hurt. We are the reason animals get well. We are the reason of whether or not they are sick or healthy. WE are MOTHER NATURE. We don't allow what the true mother nature does, because we have the human emotion that can make or break us.
Just take care of your animals! Though people can tell you something you should not do in the end it is YOU who has the last word. Just make your word count - and don't put personal pride before an animal's safety and wellbeing.
