    About 30min drive from us we stoped at our first dam stop. It has alot of water lillys in it and this red plant. Can anyone id it???

    Here is andrea at the second stop. No plants found :(

    Hi Vic,

    Your water lily is the indigenous Nymphea caeruleus. Caeruleus means blue, so you can see where the name comes from.

    The other plant is a Potamogeton, mostly likely Potamogeton schweinfurtii. The gunk on the leaves could be frogs eggs but there is not enough detail on the pics. Be careful with these plants, put them in a bucket outside first to get rid of all of this rubbish as you could transfer insects, diseases and parasites to your fish.

    See also the plants that Icarus found today, they are the same as yours.

    The fishes look like tilapia to me, but which species is not clear from the pics.

    The plant/fish on the fifth pic is the prettiest of the lot though...

    :yes
    Go Wikus!
    One can sometimes find wellknown aquatic plants in dams like that, eg Cabomba etc.
    The gunk on the red plant are snail eggs!
    Pm me if you could send some with your dad...

    Gert,

    I would really hope that one would not find the exotic Cabomba or any other exotic plant for that matter in one of these dams or rivers, because then we as plant growing aquarists will have lost the battle with regard to plant imports.....

    Hmm,

    Interesting. We do have indigenous Hygrophila species in South Africa and this may be one, but sometimes along the borders of dams normal above-water plants get submerged and look like water plants, so this could be misleading. One would need a flower for a positive ID.

    Strictly speaking one should not send SA plants from one area to another, but if they are sent from Limpopo to the Cape there is no danger that they can survive in nature here.

    There is another very important aspect here and that is that we are responsible aquarists who are not going to throw plants into the next available river, so let us be sensible.

    From what I can gather this plant was well below the water line and we where at the same dam today. The dam does look like it has a fairly constant water level. I will try and go there again to see if I can find it aswell. Mabe we get lucky and fing some flowering plants. Althou I dont think we will be so lucky. Will place it in my grow out tank and see how it goes.

    Andre,

    As far as I know the genus Rotala does not occur in South Africa, but I would need to check.

    Gert,

    A while back on this forum there was a very sharp comment about how useless our scientists and botanists in South Africa are and that they had not even managed to put together a book on aquatic plants. Well, as I feel spoken to when such comments are made, I started doing my homework, and yes, there is such a document. A lady with the Department of Agriculture actually put together such a book over ten years ago. I did not follow this up any further, and your questions here actually prompt me to follow up this matter again. Let me see what I can find.

    No Wikus, stop!

    If you put those plants in bleach they will die straight away. Put them into a large bucket and over a week repeatedly change the water to flush away any pathogens. You can also wash the plants in a solution of Potassium permanganate (I need to check the concentration), which is much milder.
