Anyone know what this is?
« on: July 08, 2012, 04:37:37 PM »

I am not sure what this is or where it has come from but I found two of these in my tank. I have described it somewhere in one of the other threads and someone said they think it is a limpet but I thought if I posted a picture one of you might just be able to ID it and tell me for sure what it is. It is the blurry white thing in the middle of the picture. Sorry it isn't very good quality but it is tiny and I took it on my iPod lol, it is also the best of 4 pictures I took of it.

they really are. the shell is relativly flat, and hangs over the body. When I got it out to have a look at it, the shell looks kind of like a clam shell just only on the top. It's really weird. I have looked up limpets and it does look a little like that.

The thing is, how on earth would you have gotten a limpet of all things in your tank? I know limpets can move around, in fact some types can be quite territorial and would ram another limpet out of the way, but I never thought they moved all that fast?
But then again I only really know a teeny bit about marine limpets.... Let's see about fresh water ones...

Could it be these freshwater limpets? They are named Acroloxus lacustris;

Perhaps they hitch hiked on some plants as babies and now they've grown you can actually spot them?

Since freshwater limpets, Acroloxus lacustris, are so small and also move really slowly, it might be hard to identify them as snails. They are small and can't do much damage to plants, but since they are small, it's impossible to find and remove eggs and the baby snails. Harmless.

Something that looks a bit similar are Nerite eggs. They are singular, white, hard, round or oval shaped and about 1 - 2 mm in diameter.

Really as I could really do with trying something like that. Someone told me they wernt very good. Aren't they tropical though? Would they be alright in a coldwater tank or is there an alternative for coldwater tanks? Also if I did get something like that are they ok with fish (mainly my fry) would they eat them? Im also worried about my apple snails I love them and don't want them to be hurt, do you think they would be too big for a snail eating snail?
Both my snail tanks are completly over run and some have found their way into the 28L with the fry and are taking over in there.

You could just bait them with vegetables, I find brocolli is best, people say lettuce, but honestly if I put lettuce and brocolli in my snail tank, I can guarantee you they'd be on the brocolli!

Do you share equipment between the tanks? That can sometimes be how snails get into other tanks.

Not too sure on assassin snails as I've never looked into them.

assassin snail is a predator, and it will eat any small snails it can catch. It will likely eat fish eggs too, and quite likely immobile (“wriggler”) fish fry too. But otherwise it is an excellent community tank resident. It does not harm snails that are substantially larger than it is, and things like adult Nerite Snails as well as Tylomelania seem to coexist amicably enough. Fish are at no risk at all once mobile, and even livebearer fry are ignored.


Tylomelania spp. are essentially non-predatory so far as aquarium fish and invertebrates go.


On the other hand, like all snails, Clea helena and Tylomelania spp. are vulnerable to predation when kept with large fish. Cichlids, pufferfish, loaches and certain catfish (e.g., Synodontis) are likely to view Clea helena and the smaller Tylomelania as potential food. Even if they don’t eat them outright, fish that like to peck at things may stress these snails sufficiently that they’ll cause damage and eventually death.


Good companions are things like tetras, non-nippy barbs, rainbowfish, livebearers, Corydoras catfish, bristlenose catfish and so on.

They would be going in with my platy's which are live bearers and the other tanks are just snail. I have tried that, lettuce, cucumber and broccoli but it doesnt reall work. I sometimes get one or two but then what do I do with them? I can't kill them all I do is put them in on of the other tanks. Although scrivens you never answered I thought they were tropical not coldwater?

Awesome! Thank you! I think I will go next week and get some. How many would you recomend one per tank or two?

Strange that none of the vegetables work? I stuck some blanched brocolli in my snail tank and I swear at least half the population of the tank had gang piled on to it, munching away XD They go mad for spinach as well.

Good luck with the assassin snails though Smiley

In the actual snail tanks the do gather on the veg but I just can't hurt them myself or put them down the sink and I can't release them onto the river bank as they aren't native to here. So unfortunatly assassins are the only way for me to go but I didn't realise they would be ok for the tanks. Didn't want to get them and end up killing them.

I know I think they look amazing. I actual fell in love with them when I saw them and now I know I can get some and that I have plenty of food for them I am really excited. Do they eat other stuff like veg or just snails?

they'll mop up any left-over flakes. Basically protein eaters but will take a bit of rotten veg
