so as a quick guide the baddies are generally long whereas the good ones are more round?

Lastly

THE UGLY

Humans


  • Get a permit
  • Keep to the daily limit of 15 per day
  • Confirm first before coming home
  • Get yourself an identification book
  • Post request for ID on MASA if unsure
  • Only take what your tank can handle
  • If you still not sure, put it back


Leave the big tiger cowries. Unless you got a big completely green tank, they will starve eventually.

Excellent observation.

YES.

Generally, if the opening is round, the snail could be a goody.
If opening is oblong and or narrow, then they are most likely baddies.

And the best scavenger we get locally, Nassarius gaudiosus:



About 15mm long, buries in shallow sand under rocks. Shell is quite glossy.



And you sometimes get this one on sandbanks in the estuaries north of Durban (Richards Bay etc):

Anyone know of or seen this species? Pic doesn't do it justice, has a blue trimming right around

Bubble shell, Hydatina physis. At certain times of the year they're super common...like 10 per rockpool. They eat small polychaete worms, so if you have a deep sand bed in your display then they do quite well. Short lived species though, even in the wild. I've had tiny ones grow to max size in a few months, but never had one last longer than a year.

Thanks for the info! first time I've seen one in East London, but that probably because I've never been looking for snails!

Had one of those bubble shell snails the first time I collected snails.

Cruised around my DSB for about 2 months then it died. DSB most likely too small to support the number of worms the snail needed.
