I have borneo (malaysian) swords and they just aren't doing well. They're browning and just falling off slowly. What should I do? Is it that they need gravel? They're in sand currently. Do they need a chemical pick-me-up?
In which one of your tanks are the sword plants? And what is the wattage over that tank? Could well that it's lighting that is too low. I don't know whether swords "love" gravel, but my guess would be that they prefer finer substrates, and substrates that are generally set up for a planted tank. My swords also don't do too well. They're alive but I also have some leaves decaying over time. I remove them regularly. Somehow the plants are still alive. It must be luck because they're rather at least moderate light plants and my light is VERY low!
It's probably your lighting. I don't think the gravel would be an issue. I have seen them in all types of tanks. Lighting is usually the problem with these plants since most tanks have only standard lighting which is usually not enough for swords.
The top one, aglaonema simplex. I saw a guy walking around WalMart with "aquarium lighting for plants" or something like that. It was a strip light and I probably could use what he had. I wonder what section that'd be in...I should have asked.
