Blue Neon Goby fish is a parasite eater fish. They keep the aquarium free from parasite so it is often preferred by aquarist. They’re also known as Gobisoma or Elacatinus or simply neon goby. They’re found in tropical reefs of Gulf of Mexico, from Texas to Belize, western Atlantic. In the wild they live much longer than in captivity. In home aquarium they live for about 2-4 years. As they’re parasite eater so rarely require much care from aquarium keeper. They’re reef tank safe and often lurk around live rock in the tank.
Other species of goby fish include : Yellow watchman goby, Firefish goby.
Size & Color: They’re small torpedo shaped fishes and has size of about 2 inches (6 cm). They’ve dark body with cyan or blue colored stripes on their body. Most of the time you’ll see variation in this stripe as per species of neon goby. But mostly you’ll find blue neon goby in the aquarium shops. Their pectoral fins are circular and transparent while dorsal fins are split in two.
Ph & Temperature : You need to maintain temperature of about 25°C – 28°C and ph should be set for 8.1 – 8.4 with carbonate hardness of about 8 – 12°dKH. Make sure you maintain atleast 30 gallons of tank if you want to keep this fish.
Breeding: You’ll find it hard to differentiate male & female. They do breed in public and home aquarium. Pair protects it’s eggs and tries to defend it from other predators. Fry takes week or two to hatch and are ready to accept food just like mature neon goby.
Food: Most of the time they surf entire tank in search of parasite and algae. If they find any parasite on another fish body then they’ll not hesitate to eat parasite. This is the reason big aggressive fishes keep neon goby alive. So other than parasite try to give them vitamin enriched flake foods, frozen and live foods. You can also give them frozen arine carnivore mixes which comes in cube. You can either order it from amazon or get it from local aquarium shop.
Behavior: At all cost don’t place them with other goby species cause this will result in conflict. You can place a pair in the tank or just keep only one neon goby in the tank. They go quite well with other non-aggressive and semi-aggressive fishes. Like other goby species neon goby is also territorial. They also prefer staying near live rock or substrate.
In aquarium shops they’re available at price of about 25-30$. When you introduce them to new saltwater tank make sure you add them first into the quarantine tank and clean them before adding to new tank. Once they’re placed in new tank and if are getting proper diet there is no need to look after them much and because of their cleaning service they’re one good addition for your saltwater tank.
