What else do you have besides the clowns?
But some suggestions are blennies, gobies or wrasses

hmmmm man there are tons of fish to choose from but being new mabey start out easyish like a purple pysdochromi or mabey a sunrise dotty which both can be a touch mean, hmm mabey a royal gramma or a lawnmower blenny
or a scooter blenny they have lots of character but can be a touch finiky to feed
watchman goby is a good choice handsome fish
stay away from damsels unless you really like them
i really dont know what else is a good fish for you but engineer goby's are pretty cool
copy paste lol

Scooter blennies are actually dragonets, like a mandarin, which is why they can be finicky.
I'm going to have to say a goby. I love mine. He's always tooling around the tank.

You have a horseshoe crab?
You are aware that they get to be a foot big? And i dont think they do well on crushed coral substrate.

Considering your tank has only been up for a few months, i dont think you would see much growth.
Also, they need to be on a finer substrate than what you have. They are detrious eaters, finding stuff in the sand. Your tank is so young and so small i highly doubt there is food for him in your sandbed, so you should be feeding him bit of chopped up shrimp or mollusks every few days.
Also, even at a size of a few inches they need a sand bed of at least 3 inches, and deeper as they get larger. They also need a large sand bed area. They also require a tank size of 180+ gallons. They are also notorious for digging around and causing rockslides.
Not to mention that most horseshoe crabs are temperate species, requiring cooler temperatures than we normally keep our tanks at.
Please return those animals to the store so they can go to homes that are much more suited to their needs.
Here is some more info on them if you're curious:
"Horseshoe crabs are not true crabs at all, but actually much more-closely related to spiders. They are also inappropriate for mixed invertebrate aquariums for many reasons. These "crabs" need to be kept in large, specialized (non-reef) systems that are have great open surface area and sand of depth. Definitely not recommended for casual keeping in small home aquaria with coarse sand and dense rockwork. The most commonly available species, Limulus polyphemus commonly ranges from Nova Scotia down to the Gulf of Mexico and grows to 2' long X 1' wide (60 cm X 30 cm). Several other species are seen in coastal waters from Japan to Indonesia, but do not appear in the US hobby."
Overview of Limulus polyphemus
By any definition, horseshoe crabs are ancient relics of the past. They have not changed much in the last several hundred million years dating back to the pre-Cambrian era (and are closely associated with their fossilized relatives, the Eurypterids). It is no wonder why they are described so often as "pre-historic". The design of their body has facilitated their long survival through the ages with its strategic and fully encompassing hard shell. Limulus are also extremely hardy in the present wild... enduring severe extremes of temperature and salinity. They are also said to be able to suffer seasonal famine and live without food for as much as a year! A year is also about how long it takes for these crabs to starve in mismatched marine aquariums. Too often, horseshoe crabs are placed in small aquaria with lots of live rock and not enough sand to burrow, forage and survive. Mind you that an abundance of live rock is very beneficial for reef aquariums. The problem is that these creatures, though, do not live on the reef proper. They do live near the reef, however, and will thank you very kindly if you provide a large open bed of deep fine sand for them to dig in. It takes perhaps 10 sq. ft per crab of more at >6"/15cm depth). It is interesting to note that horseshoe crabs may stay buried in the sand for days or even several weeks at a time. Let's be very clear that they live or die in captivity by the presence of deep fine sand and mud and the food they find within. We recommend using finely minced clams and clean Tubifex worms (live or thawed frozen) as part of the staple diet for this creature in captivity. Other ocean meats may be taken with equal enthusiasm. Be very mindful of the size and composition of food offered; Limulus have no jaws to chew or crush prey but instead process food with bristles at the base of their walking legs (yes... they must walk to feed, as the food is passed and mashed by these bristles). Although hardy and peaceful in their natural habitat, these "crabs" do not fare well in captivity outside of large, mature specialized aquaria. They tend to linger for some months in captivity, but again, do not survive past a few months with casual care.
Limulus are not true crabs at all, they are rather distant relatives of the spiders, scorpions and even the lowly ticks. Aspects of their phylogenetic relationships are suggestive when you observe their anatomy. The most obvious similarity is their prominent pair of compound eyes. In fact, in addition to the conspicuous pair of compound eyes, these crabs have a second pair of simple eyes on the front side plane of the body. A horseshoe crabs vision is not for feeding however, but for evading predation and finding mates. It is estimated that their range of sight is about 3' (~ 1 meter). Limulus also have 5 pairs of "walking" legs and two specialized pair for feeding and pushing sand, the forward pair on males being distinctly thicker and larger. Perhaps the most distinguishing part of these creatures is their telson (tail). This aspect of their anatomy performs like a rudder for balance and navigation as well as providing ever-important leverage to right themselves from a vulnerable overturned position. Its also quite a formidable weapon (although not its primary purpose) with spines and "timeliness" when thrust erect to ward off a would-be attacker. Despite the armor, horseshoe crabs are in fact rather peaceful creatures. They seem to be fairly indifferent to each other and anything that's not interested in eating them. They are somewhat generalized scavengers that consume many different things strongly preferring polychaete worms and mollusks in the sand. Their natural feeding habits keep them very active at night though in captivity they are willing to feed most anytime of the day if stimulated. This is a large part of the reason why they starve in most aquaria- few are placed into systems with aged, deep mature sand beds that have adequate populations of food organisms to sustain them. It is estimated that Limulus grows approximately 25% with each successive molt for roughly the first decade of life until they reach maturity. Molts occur every 7-10 months naturally.
Reproduction is a bit of a ritual during high tide (full and new moons) in the spring or early summer each year. Droves of Limulus migrate to the shoreline to spawn and lay staggering amounts of tiny green eggs. A large female may lay as many as 20,000 eggs which are deposited in a series of holes that she digs along the water line. Copulation is a bit of an interesting display. The males of this species (characteristically smaller than females by about 30%) grasp a hold of a female as she leaves the water to make this run. They are dragged along as the females climb up the shoreline and fertilize each batch of eggs as they are pulled across each pit dug by a female. Wave action covers over some of these nests but numerous Limulus eggs are contributed to the food web above and below the water (fish, birds, etc). In aquariums, many fish will prey on small and young horseshoe crabs. Their chitinous shells have not become sufficiently hardened and they will suffer from repetitive harassment of even curious fishes like large tangs and angels. It should be no surprise that triggers, puffers and eels will readily predate them. It is also quite unnatural for them to be kept with cnidarians and forced cohabitation will usually lead to Limulus dying in the tentacles of an anemone, or large polyped coral. Keeping these crabs in captivity also has very practical implications for their metabolism and increasing size. Before you purchase one, ask yourself if you have the means to keep them as an adult as 16"- 24" (40-60 cm) if and when they are ten years old? If you plan for a full healthy life and lifespan for this creature as you would for any other household pet like a dog or cat, you will quickly realize the very special needs of this fascinating "crab". Our purpose here is not to discourage the popular keeping of this marine creature, but to discourage the improper keeping of it. In a simple sandy lagoon or shoreline display, Limulus polyphemus are remarkably easy and entertaining to keep.
Horseshoe crabs- beyond aquaristics: Although Limulus polyphemus are still observed in great numbers, natural plights and human activities have impacted their once abundant populations. Some states in the US have established protected Limulus sanctuaries on assigned beaches. These agencies have sadly followed the lead of governing bodies before them forced to protect their natural resources like the Japanese with now endangered Limulus. The US Federal government has even imposed regulations on the bleeding of horseshoe crabs for improved survivability on catch and release. The unique blue blood from horseshoe crabs has been studied for about fifty years for its remarkable medical properties. Research has focused on anti-bacterial and anti-clotting aspects and the substance known to medicine as Limulus amoebocyte lysate (AKA- LAL). An injured crab uses this substance to quickly clot and disinfect a wound. Medical science uses it to verify that human drugs are bacteria-free and safe. Blood harvested for this research is said to fetch $10,000-15,000 per quart! Sounds to us like somebody needs to either discover how to synthesize it, or how to breed Limulus commercially. Horseshoe crabs have other economic and research values. Their eyes have been studied to enhance our understanding of how the human eye works. Chitin (chitosan) in their shells can be used to manufacture contact lenses and cosmetics and is also said to have nutritive value in homeopathic treatments. Commercially is has been used as a metal sponge in waste water treatment, and medically is can be used to make hypo-allergenic sutures for surgery. Numerous other uses are being researched from this unassuming yet valuable creature. Conservation starts at home as they say. As aquarists, please be mindful of your contribution to the use of this precious living resource. Good aquarium husbandry of this and any animal we keep serves the species through improved awareness and understanding.

A non-sandsifting goby or dartfish(firefishes) is what I would choose for that size tank.
