Hi everyone, I just lost my first fish & Betta on Saturday. I made so many mistakes with him, it breaks my heart because those mistakes cost him his life. I had him only 9 months. I have learned a lot from them though & feel much better prepared. I have his 10 gallon heated, filtered tank that I would eventually like to populate with another Betta. It has 3 moss balls & the rest is silk plants. My plans are to get tank mates for this future Betta. I'm thinking a Cory for a bottom feeder & a school of Cardinal Tetras. Would this overpopulate the tank? I read mixed reviews when I research it. Also, possibly a small piece of driftwood. Opinions on this? We wanted to get Blue Ocean some tank mates but have read it's better to establish the community before adding the Betta.
