I'm so happy I found this thread! I will be a beginner betta guardian with this tank. I've been waiting since December to get it since I ordered it with their Kickstarter.
Freyja - If you look at the pictures on the website, you will see that the amount of air that is in the tank is based on how much water is in there. I will not be filling mine up to the top. I'll also probably have a water heater cord coming out of my feeding location to vent more air into the tank.
It looks like there are Hydroponic water conditioners that should be used with the food plants.
The website says that the AquaFarm will include "Fish food and water conditioners to get started right away"
I'm thinking about adding a small water plant of some sort to reduce the betta's stress a bit... also maybe a marimo moss ball, a snail or some ghost shrimp into my tank. What do you think? Will it all fit?
