Probably still a long while off, though when I was interested in saltwater it was the marine betta that I wanted.Glad I could help!! Feel free to ask me any questions you may have if you are unsure, I am still new and by no means an expert, but at least have some experinece.
When someone said something similar to me it helped give me a little a push towards it. I am so glad I did it, don't know why it took me so long.
I keep my 750L tank as freshwater, small 40L as planted and my 150L as Marine. Its nice to have different set ups to look at.
Currently tank is filed with freshwater and highly unlikely to not be in a good while.
