I was moving 2 of my guys to their new upgraded tanks and was using the one Walmart cup I have that I got when I got Spyro to scoop them up in. Now, I've been using it, nothing new to me, except I actually read the sticker on it explaining care for them. And here I wondered just how some people get the wrong info...
On the cup it said:
Feed betta every other day.
Change 25% of the water when it gets dirty.
Use Spring water for best results.
Those were the exact wordings. <bangs head on desk>
