That's so funny.
I had been "out" of fish for YEARS until one day, a few months after loosing my dog to cancer, I wanted a new friend and I suddenly had the thought "I'll get a betta!"
Yeah, that was about a month ago. I found one beautiful boy and set him up in a medium pet keeper. Well, soon after I decided he needed more room, so I put cycled a 5 gallon and he's now enjoying his new home.
I then found another boy that I couldn't stop thinking about so I had to go get him. I was worried about keeping him in the pet keeper, but I didn't have room for another 5 gallon. But I DID have room for a 3.5 gallon!
And, I'm now cycling ANOTHER 5 gallon tank. I have really been wanting one of those "kings" and after seeing several last weekend I knew I was helpless. I haven't gotten one yet. But the tank will be ready when I find him.
The reason I went with something bigger than the keeper I've already got is that I didn't want to be changing water in multiple containers every other day. I've worried about getting a betta and keeping them in "small" homes like the medium keeper and I thought: People get these beautiful fish every day and put them in teeny, tiny little bowls. They don't change the water or keep them heated and the poor fish usually die a cruel death. At least with me they have a couple of gallons of clean water to swim in, good food, warmth, and someone who actually cares.
I also am extremely grateful for the folks on this site (even if they *are* betta "enablers" who encouraged me to get the second one!!!).
