Saltwater Fish & Inverts

(237 items)

Adding fish and invertebrates to your saltwater aquarium is more than just choosing what looks good—it’s about introducing healthy, compatible animals that will thrive in your system. At Top Shelf Aquatics, we offer a curated selection of saltwater fish and inverts that are maintained under stable, monitored conditions until they’re ready for your tank.


Our fish systems are kept at therapeutic levels of copper to reduce the risk of parasites and support strong, clean livestock. All animals are observed for feeding response, activity level, and overall condition before being made available. Invertebrates are housed separately in copper-free systems to ensure their health and sensitivity are respected.


Whether you're searching for peaceful community fish, a dependable cleanup crew, or a standout showpiece, you'll find well-conditioned, reef-safe options across this collection. Every animal is selected with long-term success in mind, and our team is here to help you make confident, informed decisions.

Saltwater Fish & Invert FAQs

How are TSA’s saltwater fish and inverts different from what I’d find elsewhere?

At Top Shelf Aquatics, we prioritize long-term success and stability with every animal we offer. Our saltwater fish are held in therapeutic copper systems, which help eliminate common external parasites before the fish are listed for sale. Each fish is monitored daily for eating response, coloration, and behavior.

Invertebrates, which are sensitive to copper, are kept in separate systems where salinity, temperature, and nutrient levels are tightly controlled. Whether you're ordering a tang, a goby, or a group of trochus snails, you're getting livestock that’s been cared for with expert attention.

Are your fish quarantined before shipping?

We do not follow a traditional, medication-based quarantine protocol. Instead, all fish are housed in therapeutic copper systems that help suppress and eliminate most external parasites during their stay with us. While this isn't a replacement for formal quarantine, it does offer a cleaner and more stable starting point for your home system.

We always recommend following your own QT process if you're managing a disease-free display or stocking a high-value tank—but we’ve designed our holding systems to reduce the risks many hobbyists worry about.

How do you ensure invertebrates are healthy and reef-safe?

Inverts are housed in dedicated copper-free systems tailored to their sensitivity and biological needs. Our team monitors parameters like salinity and temperature daily to ensure conditions are stable, and livestock is only listed after showing proper feeding and activity behavior.

We also take extra care during packing, using appropriate water volume, oxygen, and insulation to minimize stress during transit. Whether you're ordering shrimp, crabs, snails, or other reef-safe inverts, you can trust that they've been handled with care.

How do I know what fish and inverts are compatible with my tank?

Each product page includes care notes covering reef-safety, tank size, temperament, and dietary needs. If you’re unsure about compatibility or introducing a new animal to an established tank, our team is happy to help. We’ve worked with thousands of reef systems and can give you personalized guidance based on your tank’s parameters and livestock mix.

What happens if something goes wrong during shipping?

All livestock is shipped overnight in insulated, temperature-controlled packaging. We ship Monday through Thursday to avoid weekend delays, and each order is backed by our live arrival guarantee. If anything arrives in poor condition, just reach out with a clear photo and our team will take care of you. We know how important these animals are to your system—and we treat every shipment like it's going into one of our own tanks.
