    One more thing. If you put into your tanks a lot of food for your fishes and other inhabitants, these snails are likely to scavenge the leftover food scrapes rather than go and hunt for food. The snails saves more energy scavenging rather than catching and extracting a living snail to eat.

    I have a morbid vision of this snail zapping a sleeping fish instead of an MTS.

    bryan, you've been watching too many Alien movies... hahaha

    Anyway, just found out the term for the diet of live snails. These carnivores are molluscivore "slurpers".

    See Wikipedia, Molluscivore, http://en.wikipedia.org/wiki/Molluscivore (as of Apr. 25, 2008, 07:47 GMT).
    A molluscivore is a carnivorous animal which eats mainly molluscs. Several species of pufferfish and loaches fit this category. As many molluscs are protected by a shell, the feeding techniques applied amongst molluscivore fish are highly specialized and usually divided into two groups; "crushers" and "slurpers". Pufferfish tend to be crushers and will use their beak-like teeth to break the shell in order to gain access to the meat inside. Loaches are specialized slurpers and will make use of their characteristically shaped snout in order to grab hold of the animal living inside the shell.

    My snail seems to be sitting at the water surface all the time, never move. Anyone knows why?

    I have quite lots of this snail. I have collected them on a fish collecting trip to Khao Yai, & Saraburi. So first of all they are not native to Sulawesi. And when i had a pest snail attack on my 120lt planted CS tank i placed 2 of these guys in it and within 2 weeks there was a real reduction on the number of pests and at the end of 3rd week i saw not pest wandering around. I kept feeding my shrimps as usual and they were totally not interested in the flakes. But it was fun to watch them moving fastly to get a new pest... I haven't seen them eating algae, my zebra nerite snails are handling this case. So i advise any of you guys who have a problem about pest snails. Oh by the way in Chatuchak market here one of them is sold for 40THB which is less then 2S$.

    I just got five from C328 last night.
    Immediately two started to burrow into the substrate.
    Now only one of them is out and about.
    So if yours go missing don't get too worried.
    Anyone else observed this behaviour?

    Does anyone knows if these snail prey on limpets too ? (Acroloxus lacustris)

    I got lots of these limpets in my crs tank...a little eye sore.. it would be good if these snail can help to eradicate it.

    manage to take a pic while it was feeding. as my ramhorns is breeding like crazy i have to get another 2 to speed up the proccess before the whole tank is overrunned. so far i am very happy withthe results.

    i am still hestitant to put it in my CRS tank because i got a 6 year old zebra snail in there. guess i will keep catching those ramhorns and throw them in my sulawesi tank.

    After deciding that picking out MTS as part of my evening activities was kind of loser-ish. I finally got one from my neighborhood LFS. I hope it works. At the moment it just cruises around the tank waving it's thing around like Queen Liz. My wife took a look at the snail and said it was obscene. The MTS went on with their daily routine of looking disgusting.

    Very slow feeder, hardly makes a dent in a snail infestation. But interesting to keep in the aquarium.

    Yes it eats MTS.

    Does anyone know if this snail feeds on shrimps? I just got one from C328 today together with 2 Sulawesi shrimps. The uncle pack the snails with the 2 sulawesi shrimps together.

    When I reach home, I found the snail wrapping itself over one of the shrimps! Now the shrimp seems to be dead or stunned. Just lying on it's side. Went back to C328. Uncle say just get a new shrimp. for C328.

    Now testing the snail. Quarantine it with 2 cherry shrimps. Wonder if the snail will hunt the shrimp.

    Given that the requirements of Sulawesi shrimps (alkaline) and A. helena (acidic), I don't think it's a good mix in any case.

    As for shrimps, I have yet to see any pictures of the snail in the process of eating a shrimp. Therefore, even if there are reports that shrimps are part of their diet, take it with a pinch of salt.

    As always, if in doubt, then don't mix them.

    I guess the snail being carnivorous wouldn't pass on a dead shrimp or fish, it doesn't have to shuck its meal for once. Your shrimp was probably on its way to shrimp heaven.

    the shrimp was probably dead. even ramhorn do not pass a dead shrimp.

    Hi just got two of them last friday. So far no movement on my ramshorns yet. And they do burrow into the substrate like MTS. My main concern is that do they bred easily? No point in adding a predator that create the same problem as its prey.

    They are supposedly gonochoristic, i.e. you need a male and a female to reproduce. So even if you have a confirmed pair, there won't be a population explosion like what you have with hermaphroditic or parthenogenetic snails.

    Snails like pouch/pond and ramshorn are hermaphroditic, i.e. having both male and female reproductive organs on a single individual.

    Parthenogenetic is an asexual form of reproduction where the offsprings develop from unfertilized eggs (fertilization by males isn't necessary). Malayan trumpet snails reproduces primarily by parthenogenesis (although they can technically reproduce sexually), often inaccurately mentioned as being hermaphroditic.
