Are they flakes made just for Bettas?
And for the tank the Eclipse is nice, but the walmart tank is decent. I would go for the cheaper walmart tank if I had room.
Depends on how much you want to pay for a "hidden" in hood filter, vs clipon walmart.
Also I beloved the eclipse 3 is plastic, which in my past I always manage to scratch.
I only got a 2 gallon recently because I want to beable to move my beta easily. On hot days I'm going to be moving him downstairs. (my roo gets well over 90 on a hot day). My next choice was the walmart tank.
