This species is very hardy and is an excellent choice for a beginner aquarist. It should be housed in a 30 gallon or larger aquarium with plenty of loose coral rubble, and requires ample swimming room with a sand bottom for burrowing. It is important to note that a tight-fitting lid is essential, as this species may try to jump out of the aquarium or other small opening. Furthermore, it is rarely aggressive towards other fish, making it an ideal candidate for a community tank. With its hardiness, it is a perfect choice for a beginner aquarist.

This Blue Gudgeon Dartfish is a carnivore, requiring a diet of mysis shrimp, brine shrimp, table shrimp, and frozen food preparations. Its feeding habits involve picking food from the substrate as well as suspended in the water column. To ensure that this fish gets the nutrition it needs, it should be fed a minimum of three times a day. With a balanced diet, this fish can live a healthy, long life in captivity. Furthermore, it is possible to observe the fish feeding, which can be an enjoyable experience for any aquarist.

If you are looking for a purchase size that falls within that range, the approximate purchase size for a 2″ – 4-1/2″ necklace is between $10 and $20.
