Ptereleotris is a genus of fish whose species are peaceful (nearly too peaceful), unique in appearance and activity, well sized for aquariums and each are gorgeous in their own way. Perhaps the prettiest of them is the Ptereleotris grammica. Their iridescent blue bodies and sparkling ghttps://www.old lines are a statement in anyone's tank, and you combine this with the stunning fin shape and these fish are going to impress every person who passes by your aquarium.
Ptereleotris grammica is usually known by the common name “Lined Dartfish.” The whole genus is sometimes referred to as Wormfish, for really no good reason other than this fish's body shape is long and slender. We've seen them advertised as Many Striped Wormfish and maybe our favorite name, the Glorious Dart Goby.
In any aquarium, you should expect Lined Dartfish to be shy, especially initially as they become accustomed to your presence at the aquarium. As such, it is sometimes easier to get them to come out of hiding to eat if you feed them just as your lights come on and just after they go out. It is useful to have a nightlight in your display to help them find food during these times. Once they are used to having you around, you can move feeding times into daylight hours. When your Dartfish are acclimated, they will spend much of their day hovering in the water and will use quite a bit of energy to maintain this behavior so feeding at least twice a day is important. In house we feed them a mix of meaty foods, and Gamma Foods is always our product of choice. The daily mix changes but will include things like the full range of their Brine Plus products, as well as Rotifers, Large Copepods, Finely Chopped Prawn and Finely Chopped Mussel. In time, they will usually accept and do well on a high-quality sinking pellet like Nutramar Complete. Click here to learn more
