Three Best Starter Invertebrates for a Reef Aquarium

Inverts are very beneficial to an aquarium. They are the link from fish to coral and can provide a plethora of color, designs, personality, symbiotic relationships and even help with fish parasites and other malodies...

The Cleaner shrimp, known by its Latin name Lysmata Amboinensis is the first of three inverts that is worth it's weight in gold. Not only is it a hardy shrimp once acclimated correctly, it is a colorful shrimp that provides yellow, red and white striping along its body. It is known as a decapod crustacean in that it will clean parasites of fish by setting up a cleaning station, much like when you bring your car to the car wash to have dirt and salt removed from the undercarriage and frame. The popularity of this crustacean has grown at an alarming rate because of its cleaning prowess as well as being able to consume foods lodged within your corals and rock that fish can't reach, aiding in water clarity and decreased nutrient levels. The Cleaner shrimp gets along with pretty much all fish with the exception of certain larger fish like Triggers, Hawkfish, specific Grouper and Eels, Pufferfish and Lionfish. You don't have to worry about this dilemma, however, as these fish are not reef safe. Cleaner shrimp feed on all types of food and are not finicky. The other nice thing regarding this shrimp is you will be able to see them more often than not, which can't be said of Peppermint and Fire Shrimp.

This next invertebrate is valuable for various reasons that differ from the shrimps mentioned above. The Serpent Sea Star deems aquarists attention in that they are exceptional clean up artists. Such sea stars as the Ophiomyxa is depicted as a long five banded legged crustacean of various colors and designs that complements other clean up crews employed within a reef aquarium. These animals are very hardy and perform yeoman cleaning skills allowing them to get into tight areas on and in live rock continually foraging for detritus, uneaten foods stuff and decaying matter, ultimately reducing dissolved organics and elevated nutrient levels. The Serpent stars popularity precedes itself as an omnipotent scavenger that will eliminate waste and other contaminants ensuring a healthy substrate and water parameters, ultimately having a profound effect on the other inhabitants living in the aquarium. these animals are not finicky eaters and once food has been introduced they quickly come out from their hiding places to locate the food with their legs and consume the food by expelling their stomach out from their body to swallow the food before absorbing their stomach back in its body.

The final invertebrate in my list is a snail. A very exemplorary one at that. The Cerith snail is a snail that not many aquarists pay to much attention to as they tend to favor turbos, and trocchus snails instead. The cerith snail is a welcomed addition in any reef aquarium as it is accustomed to cleaning algae off glass and rockwork. The key to this snails claim to fame is its ability to work its magic in the substrate as well as on glass. These special snails have no trouble traveling across sandy bottoms in search of food or to get from point a to point b. Whereas most snails would fall short in this crucial step, cerith snails rise without fear of dying due to becoming stranded upside down and not having the ability to travel over substrate. Cerith snails are a black cone shaped snail that feeds similar to other herbivores, by scrapping algae growth from tank glass, live rock and equipment. They grow no larger than two inches, which is ideal for getting into smaller areas and also ideally suited for maintenance in smaller aquariums. Cerith snails feed primarily on macro and micro algae and can often bee seen below the substrate in search of algae growing there. These snails are easily accessible at most retail outlets and online venues. They are very hardy, as I have maintained Cerith snails in my tanks for 12 years now. The key is to ensure that you have healthy snails selected for stocking your aquarium right from the get go. As with all invertebrates, you need to ensure that fish and other crustaceans don't prey upon these snails. Knowing the fish you have or plan on selecting in the near future and whether or not they are compatible with each other is essential to the success of your snail population.

Having been in the marine aquarium hobby for over 40 years, I can attest that these three invertebrates make sense and will afford you a nice array of diversity and style in which these animals will help you to be successful and have a clean tank along the way. The fact that these inverts are very hardy, easy to find and each offering different attributes as far as contributing towards maintaining a clean and healthy tank, affords these three inverts as can't fail propositions for a reef tank, large or small.

Once your tank gets established, other invertebrates can, then be added to diversify your invert population to focus on other potential problems that may arise over the horizon.
