The Lined Dartfish has a gray body with black and blue stripes running horizontally along its body.

It should be housed in a 30 gallon or larger aquarium with plenty of loose coral rubble, and a tight-fitting lid to prevent it from jumping out of the tank. It requires ample swimming room and a sand bottom for occasional burrowing. In the wild, Lined Dartfish are found in pairs, and should be housed in the home aquarium as such. They are timid around larger fish and should be kept with other peaceful small fish.

The Lined Dartfish diet should include chopped or shaved seafood, brine shrimp, and mysis shrimp.

Approximate Purchase Size: 3" to 4"

Customer Testimonials

Sage S Los Angeles , CA
Currently have two of these in my 125. One was purchased from Diver's Den and the other is a non DD variant. Both are extremely beautiful and also extremely shy. One of them comes out only during feeding (hides under a rock) and the other hovers in the water column but quickly bolts into hiding if there's a sudden movement. If you plan on quarantining, make sure you offer lots of hiding spots / rocks / PVC piping for it. It will often wedge itself under one for a number of days. If you don't provide adequate hiding, they can and will jump. I rescued mine out of an overflow a couple of times before finally covering it.
