LOTS of jokers on ebay. I think people "drink & buy" & just never pay. The way the rules are set up now on ebay WAAAAY benefits the buyer. You should require PAYPAL ONLY as payment. Any serious buyers will have a PayPal account. The others are drunk or 12 years old. (Or drunk 12-year-olds.) Pardon to any 12-year-olds out there, no offense. I just know what I was like as an unsupervised 12-year-old. TG there was no internet then!!!!
Offering a "breeding" fish for $45 does weed out a few idiots, perhaps.
Do you send your own instructions for raising a healthy betta? Just curious.
