Thanks everyone. I only have a coralife 130 watt light (2 watts per gallon) but they seem to be growing pretty good. i used to add fertilizer but had an algae outbreak and didn't know if that contributed so now i don't and they still grow just as good. i don't add co2. guess i'm too cheap to buy it and would definitely need more light. of course the java moss grows the best. you guys should see the huge clump i have in my three gallon that i took from this tank. i was going to move my plants to another tank if i got the african. they would definitely destroy them if i left them.
