I slightly agree with Privet, you may need at least 6-7 or a little more depending on the type of plants and you said about having fish possibly if I'm remembering correctly, that imo might need to have 6 hours with those bulbs on. I have them for my 55 Gallon 48x13x20 in a compact top and they wouldn't be enough alone imo to give these plants and fish enough artificial light. Perhaps a more powerful light could work with 1 or 2 of them on during your wet season. Just giving ideas and trying to be infomative.
