Here's my betta in his 5gal. It was originally crypt only but I found I need taller growth instead. So I threw in some milfoil which I'm still waiting for these stems to convert to submerged growth and there's an Amazon sword in the back corner which is growing great and I can't wait till it's almost taking over the corner. There's subwassertang and Java moss on the rocks. it's very much a tank that won't look great for another 6 months when everything thickens up and grows more. Crypts have been in since December and were recently split up to fill in more sections. Mixture of Willisi, undulata and Wendti. Would love to get some spirialis or something similar for that "tall growth" if I could find it.
