They really can vary, I went to two other main chain stores over the last few days and I was very unimpressed. Called a different store to ask what kind of bettas they have, halfmoon, veiltail, crowntail, etc. and he said he didn't have any of those, just your basic male betta. When I asked what type that was, he didn't know what to say...pretty awkward.
Thank you! It was love at first site with this guy, and his colors have gotten even brighter in his new home.
