Dear all,

I am working on an article for a local aquarium magazine and would like to double check which "invasive aquarium snails" we all have. There are a number of common misidentifications, but it appears that we share the same species worldwide. Please tell what you think of the following list including the scientific names. Am I missing something or still misidentifying some species?

ramshorn snails: Helisoma duryi & H. trivolvis, originating in North America. The European ramshown (Planorbarius corneus) is not a nuisance species in aquaria.

"small ramshorn": Gyraulus sp. Do we have G. sinensis (from Asia) as the nuisance species or is it another one?

bladder snail: Physa acuta, originating in North America, but the type locality is in France. Is what we sometimes call P. marmorata from aquaria just retarded P. acuta or do we really have two species in aquaria?

trapdoor snails: Melanoides tuberculatus and Tarebia granifera originating from Asia/Africa. Of both species there are multiple clones in aquaria, which differ in shell colour and morphology.

pond snail: Pseudosuccinea columella, originating from North America. I have seen the same snail(?) identified as Radix rubiginosa, originating from Asia. Which identification is correct or do we have two species in aquaria?

faucet snail: Bythinia sp. not very often seen and always in small numbers. Has anyone identified it further? The ones I have seen appear different from B. tentaculata: the shell is shorter, more the shape of an apple snail. These are very small snails, perhaps 4 mm.

I'll cross-post this on Aquatic Plant Central, hope that on either one forum I'll get some additions!

Some apple snails (Pomacea spp.) are extremely invasive too. See here: http://fera.co.uk/plantClinic/.....pecies.pdf

Cake or death?

Thank you for your reply, and, yes, I am aware of that. Only I have to draw the line somewhere and applesnails tend to come "on purpose" in aquaria, it is unlikely that they come as hitchikers with plants like the snails which I listed above.
