I just joined the board and have lots of questions. My local fish store guru is brilliant when if comes to fish and equipment but not much of a plant guy. So here is the second of many to come I am sure. I recently ordered quite a few plants to add some red to my tank. These plants were Nesaea Pedicellata, Ludwigia Glandulosa, Eusteralis stellata and Telanthera Rosefolia, they were absolutely very healthy when they arrived and had vivid bright reds and pinks to them but within a week or so they have mostly turned green. I have read this can happen if you don't have enough lighting but I have about 3.5 wpg. I don't have co2 yet but use excell daily and seachem flourish about once a week. Any ideas?
