I've had some Anachris plants for a couple of weeks now but I see no growth, is there anything I can do?
As long as there isn't any death either just wait. Is it floating? If not how did you plant it?
Growth is dependant on lighting, nutrients, and carbon source.
Can you give us the info on your setup and fertilizer schedule (if applicable)
What spectrum and fixture? It's that sometimes the 'stock' light is pretty terrible for plants
