- Temperature: 75–82°F (24–28°C)
- pH: 7.5–8.5
- Hardness: Medium to hard water (10–20 dGH)
Feeding the Indian Butterfly Goby
This species is strictly carnivorous and prefers live or frozen foods. It may not accept flakes or pellets, especially when newly introduced to a tank.
Best Food Choices:
- Live or frozen bloodworms
- Blackworms or tubifex worms
- Brine shrimp (enriched)
- Small feeder shrimp (occasionally)
- Chopped krill or mysis shrimp
Feeding Tips:
- Feed once or twice daily in small amounts
- Use feeding tongs or drop food near hiding spots
- Remove uneaten food quickly to avoid foul water
Temperament and Behavior
The Indian Butterfly Goby is peaceful but should not be housed with small fish that can be swallowed. It’s an ambush predator that spends most of its time resting on the bottom or near cover.
Behavior Traits:
- Solitary or peaceful in small groups
- Slow-moving and passive until feeding time
- Can be skittish if tankmates are too active
Tank Mates for Indian Butterfly Goby
Choose calm, brackish-tolerant tank mates that won’t outcompete them for food or bully them.

- Mollies
- Figure 8 puffers (with caution and plenty of space)
- Bumblebee gobies (in groups)
- Dragon gobies (peaceful bottom dwellers)
Tank Mates to Avoid:
- Fast, aggressive fish (barbs, danios)

FAQs About Indian Butterfly Goby Care
Q: Can they live in full freshwater?
A: Some may tolerate very hard freshwater, but brackish is ideal. They thrive best in slightly saline environments (SG 1.005–1.010).
Q: Are they venomous or dangerous?
A: No. Despite their scorpionfish-like appearance, they are not venomous and pose no harm to tankmates or humans.
Q: Can I keep more than one?
A: Yes, but provide enough hiding spaces. A group of 2–3 can coexist if tank size allows and feeding competition is minimal.

The Indian Butterfly Goby is a peaceful, unique oddball fish that does best in brackish tanks with calm tank mates and carnivorous feeding routines. With the right setup, water parameters, and feeding habits, these gobies can thrive and become a fascinating centerpiece in your aquarium.
