[Yellow Eye Tang]

I have my baby tears in straight light under a 65w 6700k and they aren't dieing but they aren't growing much either. Interesting that yours didnt do well under dim lighting either. I just recently remade the substrate with florite and eco-complete - I also added root tabs. This was just a couple days ago though so if i see an improvement with the tabs i'll let you know. Not sure about the riccia tho.
