Sadly, they will not let me return them They have a no return policy.

On the box that the aquarium came in, it said that you could have guppy's It gave a few different fish that can live in there:
platy
cory catfish
guppies
goldfish
...and a couple of others that I don't remember.

Gal dang it, this is so complicated. I really don't know what to do
