Thiara amarula aka Spiky Marsh Snail

Recommended Posts

I had bought 10 of these originally but only 2 have survived. These are great for turning my iron sand over as they bury down during the brighter hours of the day. Anyone know what they like to eat?

Bob, might be the best one to answer, but I suspect that they feed on micro organisms and algaes hidden in mud that they live in. I suspect for many of our natives the mulm that most people religiously remove is what our natives need and thrive on.

Mine are doing well in a bare tank competing with my shrimp in my 'cull' tank. In fact they were the only snails to compete against the shrimp. The big red rams-horns and the little rams-horns snails didn't last long when shrimp densities increase. They will happily eat anything shrimp will including commercial pellets, spinach leaves, mulberry leaves, ect. I feed mine occasionally with zucchini. They are good burrowers but are also strong as adults. mine push a palm sized rock around in the tank - its never in the place I want it to be!

Bob keeps his in the same way that I do.

Another nifty thing about these snails is that they produce planktonic young, so they will never over-populate the aquarium unlike MTS or similar live-bearers.

@NoGi Has the foot always been yellow? Or is it just the light? Have you been feeding some colour enhancing foods in that tank?

Foot? You mean the colour of the snail? Not sure, I've only just been able to take some photos. I had originally thought that I lost all of them until late one night I saw 2.

Yeah the soft part of the snail - mouth, antennae, ect. . The foot is technically the bit it hangs onto the glass with, but that makes up most of the external soft parts of the snail.

I read they can get to 50mm - how big are yours fellas?  Mine are only 10-15mm

Mine are pretty much full grown, they would be close to 5cm but their shells are a bit eroded.

I do like these snails, but than I am a fan of almost any snail that is not a common Ramshorn, pond/ bladder snail or arghhh MTS.

These are a great snail, just not ideal as we found out for keeping in an acidic tank, that's one thing they don't like.

We also found them to be extremely active at night, great for turning over the soil and shrimp will follow them as they disturb the soil, really cool to watch.

These are the coolest snails and your photos are amazing @NoGi. Where'd you get these guys?

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
