I will add more soon. I had 3 but 1 just up and vanished on me, as well as 2 other ottos. I have no idea where they went! I checked everywhere and they're no where to be seen.
I'll also be adding some water hedge, creeping jenny, pygmy chain sword, and dwarf hair grass. This is my first shot at a planted tank and so far so good. It's lots of fum!
