About the Threadfin Rainbowfish

Name: Threadfin Rainbowfish

Max Size: Threadfin Rainbowfish can grow up to 3-4 inches (7-10 cm) in length.

Recommend pH: 6.5-7.5

Recommended Temperature (°F): 75-82°F (24-28°C)

Diet: Threadfin Rainbowfish are omnivorous and have a versatile diet. In the wild, they primarily feed on small insects, crustaceans, and various types of zooplankton. In the aquarium, they can be fed a combination of high-quality flakes, pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. It's important to provide a varied diet to ensure their optimal health and coloration.

Temperament: Threadfin Rainbowfish are generally peaceful and well-suited for community aquariums. They have a peaceful temperament and get along well with other non-aggressive fish. They may display some minor territorial behavior during breeding, but overall, they are peaceful and gentle fish.

Schooling or Non-Schooling Fish: Threadfin Rainbowfish are schooling fish, and they thrive when kept in groups. They feel more secure and exhibit their natural behaviors when in the company of their own kind. Keeping them in a group of at least six or more individuals is recommended.

Possible types of tank mates: Threadfin Rainbowfish can be housed with other peaceful community fish that share similar water parameter requirements. Good tank mates include tetras, rasboras, peaceful barbs, dwarf cichlids, and other small to medium-sized peaceful fish. Avoid keeping them with fin-nipping or aggressive species that may stress or harm them.

Behavior: Threadfin Rainbowfish are known for their graceful swimming and delicate appearance. They have long, filamentous dorsal and anal fins, which resemble delicate threads and give them their distinctive name. They are active swimmers and spend their time exploring the middle and upper regions of the aquarium. They appreciate a well-planted tank with open swimming spaces.

Fun Fact: Male Threadfin Rainbowfish are known for their impressive courtship displays. During breeding, males will display vibrant colors and swim in an elaborate dance to attract the attention of females. They also use their long, thread-like fins to show off and court the females. Witnessing these courtship displays can be a fascinating and visually stunning experience in the aquarium.

Perhaps the best store on island to get freshwater fish. They have a huge variety, including higher end freshwater fish (discus, puffers, flowerhorns , oddballs, ect) I’ve stocked a few tanks with their fish. They quarantine well and keep it real on how their fish are doing in shop.

Mr. Ali

Had a great experience here. I was looking for a unicorn/alicorn betta and spoke with the owner, Josh, about it. I ended up using his fish importing services to import a fish from Jakarta, and he brought in a few more white opaque or unicorn type half moon bettas too, to add to the variety in store. I got a sneak peak of the store while it was shut down for one week for a proper quarantine of its new fish. The owner knows his fish and keeps them healthy. A very different experience from a Petco or PetSmart! A Petco employee even recommended I go here for more unique betta fish. Note that they carry other types of fish too, plus Aquatic plants and some aquarium equipment. Pictured are some of the giant bettas, the alicorn betta, and i believe a beautiful ram.

Wonderful shop with lots of variety. Has the most unique selection of fish on the island, and at a reasonable price! Staff is friendly and very helpful when we have questions or concerns. Love coming here and seeing the jokes around the store. Also, Vinnie!

The owner, Josh, is not just knowledgeable about the fish, but also plants and tank issues. I am new to fish tanks and he has been extremely helpful in answering my questions and offering suggestions to make my experience easier. Parking is a bit tricky, but certainly worth it.

They have rare plants you can't find at most places. Got lucky we got a few; my husband is happy. This is one of his favorite places. They get pretty busy, so be patient. The staff are very helpful.
