Ewan: i have found out a bit about keeping marshies and de vis banded snakes:
Marsh snakes
marsh snakes are durinal, terrestrial, species often found beneth discarded building materials
to house a pair you should have a tank no small then 50cm long. cage decoration should include suitable hiding places near and away from the basking site. the cage temperature in the middle of the tank should be around 24- 28* C.
swamp snakes naturally feed on frogs and skinks, but can be weaned onto a diet of young mice. meals should be offered about once a week.
swamp snakes are very hardy in captivity and amenable to occasional handling, however if they bite, it will be very painful.
the species is live bearing, producing 6-16 young in late summer or Autumn.
de vis banded snakes
de vis banded snakes are most active at at dusk and on warm evenings,they are a terrestrial species often found beneth railway sleepers and debris
to house a pair you should have a tank no small then 50cm long. cage decoration should include suitable hiding places near and away from the basking site. the cage temperature in the middle of the tank should be around 24- 28* C.
de vis banded snakes naturally feed on frogs and skinks, but can be weaned onto a diet of young mice. meals should be offered about once a week. they are apparently one of the easiest snakes elapids to wean onto mice.
this species adjusts readily to captivity but should nat be handled, or at least with out a hook or unsless you know exactly what you are doing. they will thrash about wildly if handled in apropraitly and will bite repedly. a result in a bite can cause servre pain and may require medical treatment
they are live beares producing 3-9 young in late summer.
hope this helps mate, it did for me
