I have a 20 long with a sword plant in it that my zebra otos love. However, the sword plant is getting too big for the 20 long. What plant would you recommend I swap it out for? I need something that has the same type of leaves, just smaller. I thought of a crypt, maybe?
How about an oriental sword? They stay smaller and more compact. I was able to propagate two of them in my 20L but it was certainly crowded with like twenty small ones in there. You could definitely get away with one of them.
