i think i remember reading something like this. the only recorded breeding was by some girl in the 60s or 70s, whose tank was filled 60% with java moss and other mossy plants. eventually she got eggs. not worth it IMO
If was only done once, and that was some 30-40 years ago with minimal effort, then it could be done blindfolded now, eh? Typical tetra spawning techniques is all that you'll need.
