Hello Guys well today a friend gave me a bunch of moss, JAVA fern, and other 2 types plus some other plants that the names i don't know it and i have argonite for gravel. the plants that i have before seem to do fine but with this new plant i don't want to lose any do i need to change my gravel or is it fine and how often should i add fertilizer??
any advice i will appreciate. Thanks by the way no Co2 system is a 30gallon tank and is full of babies.
