Black Kumpay Goby (Stiphodon atropurpureus)
The Black Kumpay Goby is a beautiful freshwater goby prized for its unique coloration and constant grazing behavior. Males develop deep, iridescent blue to black tones with contrasting fins, while females display more subtle earth-toned colors. Peaceful by nature, these gobies spend their days perched on rocks and driftwood, grazing on algae and biofilm, making them an excellent addition to mature, well-established aquariums.
Although generally peaceful, they do best in groups and can be kept with other small, non-aggressive fish. A well-oxygenated aquarium with moderate to strong water flow, smooth rocks, and sandy substrate closely mimics their natural habitat. Since they rely heavily on natural algae and biofilm, established aquariums are ideal for their long-term health and activity.

FAQ
What is the ideal tank setup for Black Kumpay Gobies?
A well-oxygenated aquarium with moderate to strong water flow, smooth rocks, and a sandy substrate is ideal. The tank should be mature and established to support natural algae and biofilm growth, which these gobies rely on for food.
Do Black Kumpay Gobies require specific lighting?
No specific lighting is required, but natural light or standard aquarium lighting helps maintain algae growth, which supports their feeding habits.
Can Black Kumpay Gobies be kept with other fish?
Yes, they can be kept with other small, non-aggressive fish. Avoid species that are active or aggressive, as they may disturb the gobies or compete for space.

I’ve had these gobies for three months now and they’re very active and colorful. The males are striking with their deep blue-black bodies and bright fins. They spend most of the day perched on the driftwood, grazing quietly. My tank has been stable and the algae levels are well managed. Great for a community tank with small tetras and rasboras.

They arrived healthy and have been peaceful since introduction. I kept them in a 20-gallon tank with smooth rocks and sand. The coloration is vibrant, especially the males. I noticed they prefer areas with gentle current and some surface exposure. A bit shy at first but now they’re exploring more.

These gobies are a real eye-catcher. I added them to a mature aquarium with established algae. They seem to thrive and are always active. The females are more subdued, but the males are stunning. I don’t have to feed them extra food—just let the tank grow naturally.
