I was trying to figure out how to do cycleing for my new 20 gal tank and what I read just made me more confused. I got lucky with my 55 gal tank and somehow got it suitable for fish but I wanna do this tank right. It mentioned to have a fish that pretty much gets sacraficed but helps with the amonia and nitrate and such. But can you use a Male Betta for the sacrafice, only he lives? Because I have seen those Betta live in all kinds of horrible cups and bowls and places. They seem pretty hardy.
If anyone can help me out here that would be great. I have tried to search for information but have just become more confused. Thanks for your help!
