I had a 10 with Endlers and I've had bettas in the past. Then there was the 46 bowfront which had....a bristlenose pleco and cory cats that spawned and some other stuff that I don't remember that well. Then there was the 40B that had pearl gourami and more cory cats and some guppies. All were planted, all had meh results.
Eventually I'd like to have the 65 and the 15, I'm just wondering what to do first. I desperately needed help with the 40B and the 46 bowfront that I used to have, so I'll need help with a 65.
I wanted to try Walstad mostly out of curiosity. I've heard of the method and it looks like it doesn't require a lot of upkeep once the tank has been established. It's also one of those things where I wasn't going to read up on it unless I was going to do a project on it. I don't know, I've already got a CO2 setup and soil can get pretty messy. A 20 hex might be better anyway, I want the betta to actually have some room to move around.
