The Cerith Snail: A ‘Must-Have' Cleaner

byKenneth Wingerter

The Cerith Snail up closemanbetx3.0最新Most aquarists are already aware that snails eat algae.To be most correct, themajorityof snail species are algivores.To be sure, some have extremely specialized diets that donotmanbetx3.0最新include algae!other snails are technically omnivores, eating all sorts of thingsincludingmanbetx3.0最新algae.manbetx3.0最新Then, for marine aquarists in particular, there is the issue of algae specialization!certain species of snail eatonly certain typesmanbetx3.0最新of algae.After you start running a tank and have to go snail shopping to add to your clean-up crew (CUC) for one thing or another, it might feel as though you need a freaking degree in malacology just to be sure that you're actually getting the "right kind." This certainly makes any truly omnivorous, unfinicky and voracious snail genera such as the cerith snail (Cerithiumspp.) extremely attractive in the marine aquarium hobby.manbetx3.0最新Its willingness to consume almost any sort of algae or organic waste, as well as its general hardiness, would indeed make it an excellent candidate for the first line of defense in any CUC.

An easy first choice

One hugely nice thing aboutcerith snailsis that because they exploit multiple types of food sources, they cannot starve to death after they have depleted one source.If, over time, it seems that the ceriths cannot alone tackle one type of cleaning, then you can simply add a few specimens of a more specialized species to finish the job.manbetx3.0最新For example, if there is a persistent film of algae over the higher parts of the tank panel, you can supplement your CUC (in a targeted manner) with the addition of a fewtrochus snails.In this respect, ceriths are a good "starter snail." You can start with these little guys and then fine-tune your CUC as necessary down the road!

Another nice thing about these snails is their small size.Sure, their smallness (as well as their hardiness) make it easy to ship relatively large numbers of them safely!this helps to keep their price down, which all aquarists certainly appreciate.But their tiny adult bodies and shells have additional benefits as cleaners.For one, it means that they won't bulldoze your rocks, knocking over little frags and other small items.Even more importantly, it means that they can clean the tightest little holes and crannies (okay, maybe not thetiniest, but that's what your pods are for!).Finally, this also means that when they die they leave behind a comparatively smaller mess than larger snails such asTurbospp.

So, what is it about these snails that makes them so well-adapted to life in captivity?The whole family (Cerithiidae) has been quite successful since at least the Triassic period, inhabiting shallow sea floors.These are rarely stable environments.Ceriths almost always occur on soft bottoms (sandy or muddy flats), including sandy/muddy rubble zones, macroalgal beds, mangrove forests and seagrass meadows, just below the lowest low-tide.They are found in both tropical and temperate waters.

The cerith shell rarely exceeds an inch in length.It is long with a sharp tip (i.e.spire).The shell is whorled in a radial manner.The whorls are highly textured with tiny bumps and ridges.The animal is protected by a thin, brown, round covering (operculum) that effectively seals the shell's opening (aperture).The slender shape of the shell makes it easier for the animal to burrow through soft substrates.

Aquarium care/use of cerith snails

While they are surprisingly tough (especially compared to many other aquarium snails), ceriths should be acclimated to a new tank (like most mollusks) in a slow, gentle and unhurried manner.After that, there isn't much to worry about!

As they are strongly nocturnal in habit, you might not see much activity by your ceriths while the lights are on.However, as soon as darkness falls, these little creatures break out in dramatic fashion (dramatic for snails, anyway).At night, they emerge from the sand and rocky caves into the open to feast on anything frommanbetx3.0最新nuisance algaetodetritusand uneaten fish food.A common observation is that for such a small animal, the cerith snail has a ridiculously huge appetite.

Best of all, even though it has such a highly varied diet, the cerith snail is 100% reef-safe.It's pretty hard to imagine how Nature could have created a better CUC snail for the reef aquarium.Hardy, harmless and extremely effective against nearly all forms of tank fouling, this should be a primary component of your CUC from the very beginning!

    Good read, I was concerned if they ran out of a particular food if they would move to your corals.But you cleared that up.

    Definatley a must for any CUC!Like it says they are costco food samplers, but that also gives the varied nutrition i believe, they always seem to sustain the longest.
