So my husband and I are kinda new to this Betta world. We each currently have a betta of our own. Mine is in a 3 gallon bowfront tank, and his is in a 1.2 square tank. Seeing as I am the primary care taker of all the critters, I want to create a double tank from an old tank I have.
I have a full set up for a 20 gallon tall. But I have two questions...
1- How do I divide the tank into 2? I can't find a tank divider for a 20 tall. They are all over for 20 long.
2- What suggestions do you have for a filter system? One filter on each side, one filter on one side for the tank, or putting one filter in the middle for both.... Something else? I'm not sure.
