Well, I had a "no more tanks" rule. As in, I wasn't allowed to fill any tanks I didn't already own. So, I had a 5.5g, a 1.75g, and a 0.5g hospital tank. So, my limit was set at 3 bettas.
I had one in the 5.5,
the baby in the 1.75,
and my rescue in the 0.5, (soon to be moved to another 1.75 as soon as my new heater comes.)
Today, I was in Petsmart, looking at decor, and saw a Koi-patterned delta tail!
The (gorgeous) employee guilted me into getting him. He actually played the "he'll probably end up in one of those betta cubes, cold and sad..." card!
Needless to say, I have a new fish, in a 10g(!), with some live plants...
Apparently, nothing stops me anymore...
