Plants looking unhealthy

[titchrules]

Our plants don't seem to last very long.
I don't know what there called but there really tall and slim.
I put in plant feeder every week. But they keep going dark.
Does anyone know what's best to do?
I've also got an Anubis plant on a rock in there which the tip on one leaf looks brown.

What kind of lighting system do you have? What size is the tank and what are the inhabitants?

 

[titchrules]

Lights are interpet one is daylight the other is nightlight.
It's 64litres. I intend on upgrading the tank once I get more established with fish keeping.
The current inhabitants are
5 male guppies and 1 silver shark (there were two but he died this morning - was a poorly fish from Friday when we bought him) as of tomorrow he will be replaced with another (as wrong as that sounds).
There not kept in direct sunlight either.

Picture from set up. Just so if you can see what types of plants are in.

How many watts is the daylight bulb?

 

[Mr. Limpet]

Chances are that's stock lighting and it isn't going to be much except for the very basic low light plants.

Here's a link to a plant info site that can help: PlantGeek.net - Your Aquatic Plant Resource

I wouldn't have s clue!! At a guess I'd say 15watts?! Looks like a normal energy saving style light bulb to me! :s
