thank you for all your help the salifin plec will soon be going into a nice 90g. I had a feeling the grass was non-aquatic as it has recently started to die. It has given off lots of shoots though. Yeah i have no co2 and have low/very low lighting. Thank you for all the help i am hoping to do a revamp of this tank after christmas with better lighting and maybe co2. Can anyone recommend me a lighting setup for my tank? The hood will hold 2 bulbs. thanks
