All my plants are low light and only use flourish. I have had the Anubias for ever (7+ years) and all my plants grow slow but are very healthy.
My Java Moss is the only plant in there that grows like a weed but my shrimps love it
Oh believe me SearunSimpson, I have been very tempted to add small fish in there like Cardinals, Harlequins and the ones you mentioned. But I'm afraid they will eat alot of the shrimplets. I might add some fish later once the tanks starts to get crowded with shrimps.
