Betta's are addictive. I swore with Tofu that he'd be my only betta. That lasted a few months. Then came Tuna and Taco and I just had to save them.
Then today, I spotted a beautiful purple and white female at Petsmart. I nearly bought her... I wish I would've. I said no more after these 3 but darnit, they're addicting, LOL.
