First off, I would like to apologize for the wait in my publishing of the goldfish care guide and apologize for the long way off the betta fish care guide is. I'm currently dealing with the death of my 14-year-old cat. I don't feel that I can write a long and in-depth article right now. I published the goldfish article on the last night she was with us, but the only reason it was published is because I wrote it before she took a turn for the worse. I'm not going to leave you hanging forever.
In the meantime, you can look over the Betta Fish Awareness Day group on Facebook. Right now it is a small movement to aid in the spread of correct care about betta fish (or Siamese fighting fish). An actual Betta Fish Awareness Day has been set for 21 June in which betta enthusiasts will be out at pet stores trying to spread information about them such as the need for heaters, more than a gallon of water, and weekly water changes.
People (especially new pet owners) go to pet stores thinking they will get reliable advice from employees. Many times this is not the case, but occasionally you will come across a pet store employee who really knows their stuff. What this group wants is for the pet stores to train their employees more about proper betta (and fish in general) care. While I do believe a degree of responsibility lies with the new owner, employees that sell living animals should at least know their basic care.
