Thanks for all your help, guys. I've been doing so much research on tanks, I'm overwhelmed! haha. I may end up getting a 2 gallon because there is a really nice Fluval SPEC 2 gal that I like a lot. I'll have to read up on cycling and all that if I do decide to get it, as I believe it has a filter, which I guess I could decide not to use if I wanted to do 50%/100% water changes?
I wish I could show you all what my last betta, Petah, looked like (pronounced "Pee-tah", like Peter with a British accent
). I had pictures- some good ones too!- but I must have deleted them when he died.
He was a really pretty veiltail- a deep bluish purple with streaks of red and lighter blue on his tail. I bought Theo much later, an aqua/green streaked veiltail, but he was part of the problem I think, as I believe he was sick when I bought him. I couldn't tell, but I think the vendor lied to me about it.
Anyway, I vow to do better this next time! And post pictures!
