Problem is my LFS only carries Bacopa, Amazon Swords and hydrilla oh and ill just try to order them when i upgrade to the 15I've never had much luck with Swords my self. However I seem to be a C. Wendetti pro... I've never had a melt despite all the moving I've done to them. You could try those, hornwort, java moss, guppy (naja) grass or other such hard to kill plants. I just never seemed to get the planting right on the swords and aways killed them.
