I rescued my bettas, Usain (R.I.P.) and RayRay from petsmart after i saw their dirty bowl they were kept in. Usain died of Ich ): but i still have my other betta rayray and hes very perk and happy!
I rescued all my bettas-when I got my fist betta in 4th grade I made a sign saying "Save a betta from a cup!" My latest betta Neptune was dark blue when I got him, now he is turquiose,active, eats better, and has fuller fins!
Petco definately had the best variety/colors/assortment of breeds, and best quality water in the cups, (Meaning they were clean and i didnt feel as bad for them as i do for like walmart fish)
