    Giant Water Spider

    Posted by Miss Alice on 9th Mar 2019

    She's an absolutely giant lady. Current legspan is measuring at 15cm. A very chill spider though. The only time she's not chill is when she spots a cricket running past her and decide it's dinner time. It's also fascinating to watch her sitting on the edge hunting the few feeder fish in water end of her enclosure.

    Fabulous Spider

    Posted by Smithers on 26th Oct 2017

    Visually comparable to a great big wolf spider with really long legs - quite a nice patterning going on. Likes to stay still, but when disturbed will just dart across the water surface at lightning speeds, and if feeling threatened will tend to hide on an object underwater. This is a fabulous spider. Minibeast Wildlife's service is great. Can't recommend them enough.

    Perfect spider

    Posted by Phillip Pring on 24th Oct 2016

    Very pretty spider, also calm while handling into new enclosure. It has made itself a nice home onto of the plant next to the water
