The following starfish are considered reef tank safe:

Sea stars, commonly known as starfish, are among the most sought after marine aquarium animals. It seems no tank is complete without one. However, they aren't the easiest of animals to keep alive and healthy. The chocolate chip starfish is the one species you are likely to have success with, but there are some things you should know about it first. Below we will talk about what to look for when buying one, how to acclimate it, and how to take care of and feed it.

The Brittle Star, is a species of starfish with long, flexible limbs that have small pointed projections across their bodies. They are a deep black/dark color. Sometimes there are grey bands around some of the limbs. They can grow to a max size of ten inches in limb diameter. They are incredible scavengers and need not be fed any supplemental food. They should be kept in tanks with plenty of liverock to allow it to hide and burrow. Brittle Stars, like other starfish, can regenerate their limbs if they are injured. They are a great invertebrate to have in any home aquarium as they are incredible waste cleaners and awesome to watch roam the tank. I bought a red starfish as part of my second wave of clean up crew after cycling my tank for 6 weeks and introducing shrimps and snails at week 4.

Starfish are great additions to your saltwater aquarium because they usually move around the bottom of the aquaruum where there is sand. This is beneficial to all living creatures in the fish tank because disturbing the sand means oxygen is being circulated, which means the bacteria growing there will have more oxygen to power them, in turn increasing the chances of eliminating the threat of nitirites and ammonia. This makes the starfish a beneficial member of your aquarium, which means you should know how to feed a starfish in a salt water aquarium to take care of them. In this article, we'll discuss the proper feeding of starfish in a saltwater aquarium.This article covers a range of sea stars kept in aquaria, including the deliberate and incidental imports, the decorative and nuisance, or predatory, ones alike. The proper care of sea stars has long been an area of the hobby in need of improvement. It pains me to see fellow aquarists innocently add these animals to variously themed tanks with hardly a thought for what these creatures eat or need to survive. Many folks assume that "starfish" are simply deposit feeders that will somehow find what they need by grazing about the tank. In fact, very few sea stars can live wholly on the incidental matter that grows or collects in aquarium systems. Moreover, very few aquariums are even capable of growing enough food matter, by weight, to sustain even a single Asteroid (more about classes and groups below). In traditional "garden reef keeping," most of us strive to limit nutrients and nuisance algae by underfeeding and the use of skimmers, other grazers (such as snails, tangs, and urchins) and the cultivation of dominating coralline algae species. This tends to produce "lean" rocks and sand without much soft matter for a sea star to graze upon. In aquariums where suitable food matter does grow for surface-grazing sea stars, insufficient surface area, and hence food, per starfish is oftentimes a limiting factor. Undersized aquaria or overstocked tanks will not produce an adequate supply of potential food matter. The sobering reality about sea stars is that many slowly starve to death within a couple of years, if not mere months, of importation. Making the matter worse, a significant number of collected stars do not survive the importation process to reach a consumer's tank. To be clear, I do not mean to criticize the keeping of sea stars at large. Rather, it is my intent is to acquaint fellow aquarists with some potentially surprising realities about the collection, handling and keeping of these fascinating animals with hope for a more conscientious and responsible use of this group. Because feeding starfish is not very complicated, it is not a big issue for you in terms of taking care of your pet starfish. The important consideration in taking care of a starfish is the condition of the entire fish tank ecosystem itself. Starfish can only thrive in aged saltwater aquariums, which means your aquarium should have already established a balanced biological order first before starfish can be introduced to it. It's easy to underestimate the need for small frequent feedings (three to five times weekly) in a sea star's diet. It's even easier to underestimate the need to target feed these creatures at all. We must consider the not-insignificant size/weight of a medium sized "Chocolate Chip," "Red African," or Blue starfish, for example, which is many times the mass of some popular reef fishes that eat routinely. The size of these animals also causes serious problems without proper quarantine (QT) when a sick or dying specimen crawls into an inaccessible crevice of the rockscape and begins to decay. It's not hard to imagine what a comparable mass, like a 4 oz. package of frozen meat or a large can of food pellets, poured into the tank and left to rot would do to water quality in mere hours. QT is not only for disease control, but also for screening for incidental pests and predators carried in (flatworms or predatory snails, for example) and the simple, controlled acclimation of stressed, newly imported specimens under close supervision.
