    Default Snail Id...

    I found little snail some year ago in a river near to my home, itīs really scarce in spring, winter and autom, and really plentiful on summer. So i though it could be nice in a warm water into an aquaria, so I caught some of them and put into my tank, they was nice until I started to add CO2 in the tank, they died in the next days...
    Anyway, I think the genus would be Theodoxus, but I am not sure.
    What do you think aobut them???

    Hi Xema,
    your guess about the genus is correct. It is a Theodoxus species. I can't say yet which species it is. It could be a nice variant of T. fluviatilis. Give me a day or two to find out which species you can find in Spain.

    BTW, it is possible to keep and breed them in your tanks. I keep some of them myself and got also several times offspring. The lay a lot of eggs but normally only a few (1-4) of them hatch. The young snails grow very fast in the warm water of our tanks. In nature they would need 3 years to grow to their full size, here in Germany. In my tanks they need only 6-7 months. They feed on algae on flat surfaces. Brown algae on the tank walls are perfect for them but other algae are good, too.

    best regards

    Robert

    I found them in an isolated river (Guadiaro river) near to Jimena de la Frontera (Sothern Spain). Some Km flowing down its water are mixing with Hozgargata river, one of most anexplored (speaking about underwater flora and fauna). They flow in their upper part into the Alcornocales (coark trees) Natural Park.

    Hi Xema,
    I think it is Theodoxus fluviatilis. Take a look here: http://www.idscaro.net/sci/04_med/cl...oxus_fluv1.htm

    Yep, that's a Theodoxus .... very likely T. fluviatilis (shell differs a lot in those snails), Neritidae family ...


    Did you put them in a tank? How are they doing?
