Just got the news that all of my RCS died, I think it might be because the top of the vase is tapered and they couldn't get enough oxygen. I'm really annoyed because I spent over $30 and lots of time on the shrimp and they all died.
I picked up a 1 gallon bowl for my sister's betta. It's better than what she has at the moment (a half-gallon bowl) but still not ideal.
Yesterday I set up my cousin's 3 gallon tank (with a filter) for her birthday and she loves it, she has a female betta in it who she named Sapphire.
My betta doesn't have a name yet, but he is in a 2.5 gallon tank with a filter. He is smaller than my other betta, but I think he is going to grow. Here is a picture of him, he was swimming out of the hole in the castle as I took the picture.
