The Yellow Wartskin Angler is a great choice for any reef aquarium without smaller fishes which the Angler would probably eat. It will not bother any corals, clams, or larger invertebrates. The Yellow Wartskin Angler perches among the rocks and coral appearing to blend in with the reef. It uses its lure to entice fish to swim up to it. After waiting patiently for the perfect moment, the Yellow Wartskin Angler explodes, rapidly swallowing the unsuspecting fish. It appears as if the rock moved and the fish just disappeared. This fish works smart, not hard.
Wartskin Anglers can change color over time based on their environment. The most common colors are Black, White, & Yellow.
Maintaining Ammonia at 0 ppm, Nitrites at 0 ppm, and Nitrates below 10ppm will help to keep your Wartskin Angler happy and healthy. We recommend doing a water change soon after Nitrates rise above 10 ppm. Maintaining proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing), and magnesium levels (1260-1350 ppm) will help to keep pH stable in the 8.1-8.4 range. We recommend a specific gravity of 1.024-1.026 with 1.025 being ideal for fish. Temperature should remain stable as well and should stay within a 2 degree range.
Remember, any fish smaller than the Yellow Wartskin Angler is fair prey. It will even eat slender fishes that are much longer than it. If you ever have trouble feeding the Angler, try putting several Green Chromis or Damsels in the tank to act as feeder fish. They are reef safe and will add a splash of color to your reef until eaten. After your Yellow Wartskin Angler is well acclimated to your tank, try offering it pieces of defrosted silverside on the end of a feeder stick. Just wiggle the silverside in front of its mouth until it eats it. The first time is usually the hardest. Once the Angler tries a piece of silverside, it seems to begin to associate the feeder stick with a good meal.
You should feed the Angler about twice per week. It will eat more often if given the opportunity but will grow much faster. The larger it gets the more of a threat it is to other fish in the aquarium. We have kept Anglers for many years offering food only twice per week. Just keep their belly full and they will do well.
