https://youtu.be/YxX8_WtoW8c An up close look at neocaridina at 10x under the microscope.

The Very popular LFS in Perth sold them to me as Live Blood Worms. I'm not going to dispute @jayc. They dont look like the ones in his photo and they never hatch into anything.

Awesome shrimp! You lucky guy °°)

Looks to be US based though so no good for us aussies. May help out our OS members though.

Melanoides tuberculata, commonly known as Malaysian Trumpet Snails (MTS), originated from all over Africa and Southern Asia. MTS are generally introduced into fish tanks accidentally by being attached to new plants or used aquarium decorations. They can come in a range of shapes, patterns and sizes. Opinions on MTS are divided with most having a strong dislike to them due to how quickly they breed and take over a tank. However, these snails can also be beneficial. As they move eating detritus and leftover food under the substrate, they are also aerating it. This in turn supports root growth and air exchange which are great in planted tanks. How Do They Breed Malaysian Trumpet Snails breed extremely fast, particularly in good tank conditions. The rapid breeding abilities of the MTS is one of the main reasons they are a concern to aquatic tank keepers. One method that works well with our members here is to use some vegetables like a sliced cucumber. Turn the lights off, wait a little while and remove. You can also limit their population growth by being strict with your feeding regime and removing any uneaten food from the tank. Take note though, without the use of a chemical deterrent, which is harmful to your other invertebrates, it will be unlikely that you can remove 100% of them. What Do They Eat They are not difficult to feed. Primarily, Malaysian Trumpet Snails consume large amounts of algae and detritus. They are also good scavengers – eating leftover food and fish waste as they burrow underneath the substrate; thus, doing their share of cleaning the tank. They are especially helpful to aquarists who collect messy freshwater fish, including goldfish, and who keeps live plants. No, MTS generally do not eat live plants. You can also supplement their diet by feeding them with leafy vegetables or any plant-based fish food. Just don’t overfeed them as this will cause a snail outbreak. Water Parameters These snails are not difficult to care for as they only require minimal attention. If the tank is good enough for your fish and/or shrimp, there is a good chance that it will be fine for them. That said, if you want to get technical, they should be kept in a freshwater tank range with the following water conditions: water temperature from 21° C to 26° C pH of 7.0 to 7.5 Sources: Vogler, R.

Clea helena is one of the most sought-after species in the aquarium business as it has the capability to hunt down pest snails; thus, helping solve the snail infestation concerns in fish tanks. Except for this, they are a peaceful community tank resident. Keep reading to know more about the assassin snail. Appearance Their shells are conical and are prominent because of their yellow and dark brown stripes – adding a splash of color inside the fish tank. Unlike other species, it is not possible to tell which a female assassin snail is and which a male is. They breathe by sticking out their siphon – like other snails. Clea helena grows as large as 0.5 inch or 1.3 cm. However, there were reports of finding bigger snails. As the large snails age, they begin to lose the tip of their shell. Natural Habitat Assassin snails are found in Southeast Asia and are native to Indonesia, Malaysia and Thailand. As freshwater aquatics, they occupy small bodies of water like streams and ponds. They prefer to live in areas where there are sandy or muddy substrates. Thus, if you are thinking about placing them in an aquarium, you should be able to reproduce a habitat like these conditions. Care It is so easy to look after an assassin snail. Water parameters are not essential, but to best care for them, keep them in water with medium hardness (pH 6.5-7.5). Their appearance may seem to point out that they move slowly but the truth is that they move quickly on any surface. Anyone can notice this particularly when they are hungry – and after they are fed as they disappear immediately. Feeding They eat other species of snails and worms, but they also devour anything they can find – including decaying fish and other small or soft-bodied invertebrates. Because of this, they do not give aquarists like you a hard time feeding them. If in case the tank has a significant population of snail, then you have nothing to worry about feeding them. Other aquarists feed them with brine shrimp, frozen blood worms and others. Breeding Some snails contain both the female and male reproductive organs. When they mate, they can produce eggs or young. However, these assassin snails are born a female or a male. Because you can’t tell their sex, buy 5 or 6 of them so you can at least be sure that you will have a male and a female. They mate for about 3 to 5 hours before they separate. Shortly thereafter, the female assassin snail will lay eggs (up to 4). These eggs, in a gelatinous square with a yellow centre appearance, emerge in a straight line. Feed them meaty food as it helps in good reproduction. Lifespan Clea helena can live around two years, but make sure that the aquarium is well-maintained and they can easily exceed this lifespan.
