Silver Dollars and plants

Howzit all

I have had a pretty big algae problem in the recent pass so in an effort to create a more balanced eco-system I added a couple of plants to my tank to try prevent algae blooms. I have 4 silver dollars and I was aware that they eat plants but I thought I would give it a go anyway. They have eaten most of the plants except for the ones that are not green (red leaves). Is this due to the colour or the type of plants? Are there any plants that silver dollars won't eat?

My tank is a 1.5 meter and current lighting is an odyssea 39w 90cm unit (4 bulbs).

Thanks for any help in advance.

 

think the only plants they wont eat is plastic ones haha

 

Anubias may survive Silver dollars.....

 

(lol) .... well... then I think nothing would.... they are the most durable plants I can think of..... and I think even plastics would have to be glued to the bottom of the tank.... Sd's are destructive in that way.....

 

Java fern, I'm pretty sure nothing will eat Java ferns.

 

I've read that the Onion plant(Crinum thaianum) is not eaten by anything but who know maybe not.


I'm going to try a planted SD tank soon, but I'm giving the plants 2months to get going,but we'll see what happens.
O and I'm using fast growers, like Vallis,and hygro.

I've read some where that they don't eat red plants,and @ATV also says they don't eat his ,so maybe they don't like red.
