Lexi B Posted December 2, 2021 Share Posted December 2, 2021 I have two cube betta tanks that are 6 gal 12x12x12s. I've never tried a sword plant, but I worry that maybe they would be too large for that size tank? In particular, I was eyeballing red melon sword. I'm not worried about my light or nutrients in soil and the water column, just space. Link to comment Share on other sites More sharing options...
