Comprehensive Guide: Geometric Pygmy Hawkfish (Plectranthias sp.)
The Geometric Pygmy Hawkfish, also known as Plectranthias sp., is a colorful and fascinating species that can be a great addition to a saltwater aquarium. In this comprehensive guide, we will cover various aspects of this hawkfish to help you understand its habitat, care requirements, compatibility, and more.
Habitat
The Geometric Pygmy Hawkfish is commonly found in the Indo-Pacific region, particularly around the coral reefs. It prefers rocky and coral-rich areas with plenty of hiding spots. This species is known to inhabit depths ranging from 10 to 100 feet.
Reef Safe
The Geometric Pygmy Hawkfish is generally considered reef safe. It won’t harm corals or other invertebrates, making it suitable for reef aquariums. However, you should still monitor its behavior closely and ensure it is well-fed to prevent it from preying on small shrimps or other tiny creatures.
Size
The Geometric Pygmy Hawkfish is relatively small, reaching a maximum size of around 3 inches. Its small size makes it suitable for smaller aquariums, starting from a minimum tank size of 20 gallons.
Temperament
This species has a semi-aggressive temperament, meaning it may exhibit territorial behavior towards other fish. It is generally peaceful towards similar-sized or smaller tankmates but may become aggressive towards other hawkfish or similarly shaped species.
Sexual Dimorphism
There are no visible differences between males and females of the Geometric Pygmy Hawkfish, making it challenging to determine their sex without genetic testing.
Lifespan
The Geometric Pygmy Hawkfish has an average lifespan of 5 to 8 years. Proper care, nutrition, and a suitable environment can contribute to a longer lifespan.
Diet in Aquariums
In the aquarium, the Geometric Pygmy Hawkfish is a carnivorous species. Its diet should primarily consist of small meaty foods such as frozen or live brine shrimp, mysis shrimp, small fish, and other similar protein-rich options. It is essential to provide a varied diet to ensure proper nutrition.
Aquascaping Recommendations
When creating an optimal environment for the Geometric Pygmy Hawkfish, it is crucial to include plenty of hiding spots and caves. This species enjoys perching on rocks or corals, so providing a well-structured aquascape with plenty of vertical elements can mimic its natural habitat and encourage natural behavior.
Captive Bred Availability
The Geometric Pygmy Hawkfish is not commonly available as captive-bred. Most specimens found in the aquarium trade are wild-caught. However, efforts are being made to breed this species in captivity to reduce the impact on wild populations and provide more sustainable options for hobbyists.
Compatibility with Other Fish, Invertebrates, or Corals
The Geometric Pygmy Hawkfish can be compatible with a variety of fish, invertebrates, and corals, given proper care and suitable tankmates. Here are five specific tankmates that are good choices:
- Clownfish: These popular clownfish are peaceful and can coexist well with the Geometric Pygmy Hawkfish. They also add a vibrant splash of color to the aquarium.
- Firefish Goby: Firefish gobies are peaceful and can inhabit the lower areas of the aquarium, complementing the hawkfish’s mid to upper-level swimming habits.
- Yellowtail Damselfish: Despite being a damselfish, the Yellowtail Damselfish is known to be less aggressive and can make a suitable tankmate for the Geometric Pygmy Hawkfish.
- Green Star Polyps: These soft corals can provide a beautiful backdrop and add some movement to the tank. They are relatively easy to care for and can coexist with the hawkfish.
- Cleaner Shrimp: Cleaner shrimps are beneficial to the aquarium ecosystem and can help keep the hawkfish clean. They are generally compatible with the Geometric Pygmy Hawkfish.
Note: It is always important to monitor the behavior of tankmates and make adjustments if any signs of aggression or incompatibility occur.
