Id have been upset also by their responses. It sounds as if they are so used to uneducated people coming in and just breeding without future plans that they put you in the category, and REFUSED to understand that your NOT like that. I bred my VT male with my CT female and my babies are growing to be BEAUTIFUL and im SO proud of them, and honestly, theyve got the best care from birth to death coming to them, they wont ever look all clumpy and sad like petstore cupped bettas, they will be extra pretty and really, if a VT is well taken care of and its finnage is at full potential its just as pretty as the fancier types in my opinion! Dont let it get you down, be proud of your and your fishys hard work :)
RIP to my little Coraline.
