D. campbelli is the only one with gold stripes and a generally brown body color. It also has 4 lines.
New Guinea Tiger Datnoid (Datnioides Campbelli) Datnoids are a group of fish that are popular among owners of large fish. They generally make ideal community tank members provided all their tankmates are of a similar size. The New Guinea Tiger Datnoid has some requirements that may limit the fish that can be successfully kept with it.
Tank Setup & Tank Size
First, it requires fairly hard water with a pH of 7.5 or higher. And while it can be kept in pure fresh water, New Guinea Tigers are never found too far from the mouths of rivers opening up into the sea, so ideally the water in their tank should be at least slightly brackish.
They are a relatively large fish so a single specimen should not be raised in a tank less than 100 gallons/ 378 liters.
You may want to keep a single specimen because they can be aggressive to each other or any fish they think could be another datnoid.
However, if you do want a group, start with juveniles and get at least 5. The younger fish tend to travel together and the greater number means that the aggression will be spread out among all the members of the group, not just the weakest.
I included two Videos with this post in future. The first is a datnoid in its usual coloration. The second is one demonstrating its night colors and/ or stressed colors.
Many times in fish stores, you will find them exhibiting the darker coloration. They are a fish that can become very stressed during transport.
If too stressed, they will refuse food. Patience is needed to bring this fish out of its traumatized state. All New Guinea Tiger Datnoids on the market has been caught in the wild.
- Origin: New Guinea
- Size: 30-33cm/ 12-14 inches
- Temperature: 20-28° C/ 70-83°F
- Breeding: Unknown.
They are predators that can be fed live earthworms, chopped prawn, strips of fish, or live shrimp. Adults can be fed just two or three times per week. They are messy fish and daily feedings will result in water quality problems.
When young, provide a lot of covers. Adults like open places to swim but appreciate a shaded tank. You can use floating plants for this. Salinity can be pure freshwater to a 1.010 salinity.
