I just found out the little "spider plants" in my 5g planted tank are e. tenellus. This appears to be an aquascaping plant that could form a carpet. It has already sent out several babies amounting to about ten plants now. But it's just planted in plain wild 2" deep stream sand. The sand has worms to sift it but will there be sufficient nutrition down there? Should I just let it do its thing unless it looks to be dying or slowing down?
