Mõtlesin, et teen eraldi teema nende tigude kohta, sest tegemist on üsna haruldaste isenditega akvaariumis.
Nimelt on paaril kasutajal ReefCentralis veel sarnaseid tigusid ja tuntakse huvi nende toitumisharjumuste kohta.
Teada on, et vetikaid nad ei söö, sest neil puudub selleks sobilik seedimisorgan. Dr Shimek arvab, et nad on röövloomad toitudes ilmselt väikestest ussidest ja vähilistest.
Paljunemisest pole seal veel mingit infi, nii et ma võin selle koha pealt võib-olla esimene olla.

Sain Reef Central'ist teada, mis tigudega tegu

It's an Engina species, although there is still some disagreement about it's proper name. It's had several names in the past, and has been considered to be a form of Engina alveolata, but others believe it deserves its own name, Engina histrio, and isn't a form of that species. They are found in the same areas without intergrading, and E. alveolata are about twice as large and have orange and black markings instead of yellow and black ones. Your choice:

Sellised on need tundmatud teod lähivõttes:
Olen märganud vähemalt 2-e sellist uut pisikest tigu, nii umbes 4mm. Vaevalt, et need 2 on koos kividega tulnud ja siiamaani oma kasvult teistega võrreldes kängu jäänud, rohkem kaldun ikka arvama, et nad on mu akvas sündinud
. Way to go, selliste tigude paljunemine pole ilmselt tavaline

Hello Brian,
I have found these snails mostly on live rock, close to coral base and sometimes on sand. I don't have any problem algae, although there does appear some diatom film on the glass and probably some on the live rock also. So I think they could be eating diatoms in my tank
Rgds,
Andres

Andres,
Thanks for the reply, but we have since found out that this Genus of snail is strictly predatory, so it would not eat diatoms (it doesn't have the stomach that can digest them). Dr Shimek believes the most likely food source would be small worms or crustaceans, but no one really knows about these guys.
Brian
