[Killietalk] ramshorns

["Tim Addis" <timaddis at killifish_force9.co.uk>]

Totally off topic regarding killies but I'm experimenting with ramshorn 
snails with some great results. They are very good at clearing up uneaten 
food in my tanks. Brine shrimps & the food I sell online (not intended as an 
advert Barry) containing Astaxanthin are their only introduced food source. 
They clean up a treat. Two points which might be worthy of some discussion. 
Firstly, they are extremely red - redder than I have seen before; secondly, 
they quickly kill off the common water snail we have in UK tanks. I don't 
know if they directly kill them but loads of shells are taken out in water 
changes & they seem to overun other forms to dominate tanks.
Does the ramshorn predate other snails I wonder?
