Blue Spotted Puffer



Blue Spotted Puffer may also be referred to as the Blue Dot Toby or Blue Dot Sharp-Nosed Puffer. The members of the Canthigaster Genus are known as sharp-nosed Puffers also known as Tobies. Blue Spotted Puffer Canthigaster solandri and the Papuan Toby Puffer Canthigaster papua share similar features. The absence of orange coloration in the area around the mouths of Blue Spotted Puffer Canthigaster solandri is the main difference between these two puffers. This Blue Spotted Puffer lacks pelvic fins, however, it has been taught to use the pectoral fins for moving around the aquarium. A 50-gallon or greater aquarium that is exclusively for fish is ideal. The teeth of this fish actually form the result of a fused beak structure. It could eat invertebrates within a reef aquarium. It gets scared when placed inside a net. Hence it is recommended to use a container to move it. A Blue Spotted Puffer's diet demands an extensive diet of meaty foods, such as the clams, squid, and krill along with hard-shelled shrimp, to aid in the wear and tear of their growing teeth. Approximate size of purchase: Small: 1-1/2" to 2" Medium: 2" - 3" Large: 3" - 4" Pair: 2" to 4"

Blue Spotted Puffer Information The Blue Spot Puffer, Canthigaster papau is often referred to by the name of Hawaiian Blue Puffer or the Blue Spotted Sharpnose, has an enthralling personality. It is a fantastic fish to keep in a tank that is exclusively for fish. The body of the fish is covered with striking blue dots. It's sexually dimorphic, which means males have prominent points on the middle of the back and above the position of the gill's opening - something females don't have. It releases an toxin, known as tetradotoxin. It's found within the skin and the viscera that render them unappealing to the majority of fish. It is quick to adapt to the aquarium environment and requires plenty of hiding spots that include crevices and rocks. It is not considered safe for reefs due to its tendency to nip corals and can be able to cause poisoning in the tank. It is best kept in a larger fish only aquarium, and it is strongly advised not to include multiple species within one tank. Blue Spot Puffers from Hawaii eat heavily on red algae coralline and green algae, as well as the majority of carnivore preparations. Blue Spot Puffers are a great choice for carnivores. Blue Spot Puffer should never be kept or exposed out of the water since it could be harmful to fish.

Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
