hi i have a 38l tank (fry tank with some shrimp in) and i have half of it covered in gravel. there is jbl aquabasis on the bottom, a layer of akadama and then black gravel capping it all. it is 10 US gallons and has a 18 ich 15w T8 bulb. the tank is about 25cm deep so light can pierce through. i will post a pic of the tank later when my camera is charged!!!! anyway, my question is, what plants can i put in there, that tolerate low light levels. i want to steer away from java moss etc. i have diy co2 and dose a tiny bit of easy carbo daily and TPN. (soon to be TPN+) but i would like something that will make good use of the substrate ferts like a crypt, but it all depends on my lighting i guess. so some help is needed. cheers.
