hi, iv had about 4 plants ( don't know the name- there long and thin) in my tank since about 6 weeks ago. I usually just by fake ones because i think they look better personally but i thought i would try them any way. Anyway none have actually died as such, in fact they look really healthy and green, but they dont seem to have grown at all( like not even a millimeter! 
) what can i do?
) what can i do?
