Clithion corona is a spiky nerites from the philippines, unfortunately I'm out at the moment and trying to get more. I have one with shell degradation =( it's too crappy for anyone to want. It was the last time I buy from Sweden. Next time will be thailand export.
The olives and clithion are in a tangynikian tank with:
L.ocellatus var gold
L.multifasciatus
L.speciousus
A.compressiceps var sumbu shell
A.compressiceps var tanzanian black
X.flavapinnis var Nazac Lanc
C.leptosoma var Kantalamba Jumbo Blue
The Natalensis are in a mixed cichlid tank with:
J. transcriptus var Gombi
Aulonocara sp. var Albino Eureka Red
Natalensis are in and going fast, PM me if you want any
This is a random snail that decided to come to the top of the tank..though probably one of the nicer ones
