Wow I think its great that they would finally give these bettas some room to move around.
I wish my local petco or petsmart would do stuff like that. I always see dead bettas when I go in there. Just recently I saw a bunch of bettas that had died because their cups were completely filled to the top with water!!! I found the manager and showed her and she said "oh yeah, well sometimes we don't have time to change all their water so we have volunteers from the high school come in and help change the betta's water and then the kids get school credit, so they must have done this"
I mean , if petco doesn't have enough employees to make sure all the animals at the store are cared for then they should freakin' hire some more, not be all cheap and find volunteers to care for them. or at the very least if they are going to have volunteers then at least train them!!!
For heaven's sake, they basically drowned a fish!!!
