No, I don't have a new betta in such a short time. I think two is enough for now. But I'm babysitting my 6 yr old cousin from out of state, and we are talking. She says they keep her family betta in a bowl. So, of course, what do I do? I find my empty 2.5 and take off the light and rim because 1) the light doesn't work 2) it looks much better without it. Anyways, I ask my cousin if she wants black or colorful substrate. She wants colorful. I had some extra plastic plants and so we put them in. I also put in a Marimo moss ball. Sadly, I don't have an extra filter or heater. But at least the betta will have a bigger home with decorations to hide behind and interact with. I was slightly worried about my aunt's reaction, but she was super enthusiastic.
