I just wanted to say ... my Dad had some black ruby barbs and some gold barbs and he couldn't grow a single plant while the gold barbs were alive. Now he's down to just two black ruby females (and 5 new platies that he added at the weekend) and his plants are starting to recover. I've no idea if anyone else has had issues with barbs eating plants but I thought I'd mention it seen as you've gone to all the effort of planting it well
