Fish with big forehead are among some of the world’s strange creatures. Marine biologists are used to confronting these types of fish in their missions, but you can also see them, especially when scuba diving – You need to be patient and squint enough and wait for your moment.
If you’re not a marine biologist or a scuba diver, this post is your chance to see these types of fish with big forehead and learn a few things about them.
And if you’re a fish enthusiast, you’ll know the types you can add to your home aquarium.
List of Fish with Big Forehead
- Kamfas
- Midas Cichlid
- Dolphinfish
- Napoleon fish
- Green humphead parrotfish
- Oranda
- Humphead glassfish
- Hump-headed blenny
Kamfas
Kamfas is a Fish with big forehead .Both new and old varieties of Kamfas need water changes on weekly bases. It would be best to do water changes 20 to 30 percent weekly.
But it would be best if you kept this in mind, and you should add water of the same temperature in your tank as existing water after a water change.

Kamfas(Fish with big forehead) prefers 2-3 days of aged water in the water tank, and aged water has a minimum chlorine content due to evaporation.
Non-iodized sea salt can be a natural and safe supplement to aid your Kama’s growth and well-being. The dosage should be limited to ½ cup of salt for every 30 gallons of water. The salt should be added a few minutes after cleaning the tank with every water change.
Remember that only the lost amount of salt should be re-added when you do a water change. For instance, if you have a tank with 100 gallons of water capacity and change 30% water, then salt for only 30 gallons should be added, i.e., a maximum of ½ cup.
Kamfas prefer hard water with a PH of 8 or slightly more. Using natural buffers like coral chips inside the filter as filter media can help immensely. Using lava rocks inside the filter can be beneficial in more than one way, as lava rock has an excellent porous surface area that can be used to multiply and harbor the beneficial nitrifying bacteria in your aquariums.
As far as possible, try to restrict the use of artificial buffers such as chemicals, as chemicals are unhealthy in the long run, primarily if you use the chemical in excess.
Midas Cichlid
Midas Cichlids Fish with big forehead are also known as amphioxus citronella. These Fish with big forehead are often confused with the red devil cichlid due to their similar-looking appearance. Midas is large and aggressive that is recommended to be kept only by experienced aquarists. If you are a learner and want to keep

Behavior
Midas Cichlid Fish with big forehead belongs to the cycling family. They will eat small fish, snails, plant material and almost anything that can fit in its mouth.
If you want to keep it with other fish, have a tank of at least 55 gallons for one female and 75 gallons for one male and 125 gallons for one pair. If you keep them with other large fish, 200 gallons will be required. Keeping this fish with other fish is essential to keep them in a larger tank.

Napoleon fish
Napoleon fish live in coral reefs throughout the Indo-Pacific region. They are some of the largest bony fish found on reefs. Unfortunately, they are also endangered. Humans used humphead wrasse via cyanide, which kills the surrounding reef. In some areas, this is done so quickly the fish are unable to recover their numbers.
While they have protections in some places, others leave their populations endangered to extirpation or extinction in these locales.

They may be confused with other large wrasse species like the sheepshead wrasse, which also has a prominent head bulge, but the humphead typically displays brighter colors.
Female and male napoleon fish can be told apart as males are blue-green while females are red and orange. Like parrotfish, however, a napoleon fish may change sex throughout its lifetime. These fish are slow-growing fish. They begin life as an egg that drifts throughout the ocean.
Green Humphead Parrotfish
With the potential to grow about 4 feet long (1.3 m), the humphead parrotfish is the largest species of parrotfish. These grazers were once plentiful throughout the Indo-Pacific and Red Sea tropical and subtropical reefs.

Due to years of overfishing, they are only shared in protected and very remote areas. The prominent bulge on their forehead can quickly identify adults. Their bodies are covered in hard scales. During the day, these parrotfish gather in groups of about 10 to 30 individuals. They swim around seaward reefs and deep slopes from 3-130 ft. deep, feeding on live coral and algae. Their strong teeth are fused into beak-like plates.
Their feeding is noisy because they crunch on the coral’s calcium carbonate skeleton with their strong teeth.
Over a year, a single fish can remove over 5 tons of calcium carbonate from the reef, recycling it into the sand.
By selectively eating fast-growing coral species over slower-growing species, they help maintain a more diverse coral reef ecosystem. Sometimes they use their head bulge as a battering ram to splinter corals. They are timid when approached by divers.
Oranda
A fully grown Oranda goldfish is quite an eye-catching fish to see. They have a ton of personality, but when caring for them. They have some conflicting information found online.
Size
The maximum size of Oranda Goldfish you will read is about 10 inches, and the average they probably get is around 8 inches. They can be even more significant, 10 inches. And their tail is very long, so a lot of it is that tail, but as far as the body goes, it gets massive and comprehensive. So they are giant fish.

Water Parameters
They are flexible on this, and having stable parameters will be best for any of these ranges. 6.5 to 7.5 is the ideal range because it is like tepid water that is right in the middle of the range. Anywhere in there is going to be good.
Food & Feeding
Feeding for the Oranda goldfish is the main one; the staple is to repay super gold. So now this is a gel food that you boil some water, pour in the powder, mix it up and then put in the refrigerator and then you know after a few hours. You just cut it into little squares or little cubes, and you can make them as large or as big as you want.

Humphead Glassfish
These fish looks lovely, but they did not start living like that. They were happily swimming away in Asia, and these things were caught somewhere. They happily swam away, nobody bothered about them, and they were pretty plain fish with no colors until somebody thought up the fantastic idea of catchy knees fish.

The Humphead Glassfish, like other glassfish species, are surprisingly hardy and adaptable. Most glassfish need a brackish water environment to survive. Still, these are strictly freshwater fish, so this is simple to care for and makes a most intriguing curiosity for a freshwater community tank! They are peaceful with other tank mates but boisterous and energetic at feeding time. They have a surprisingly giant mouth and may snack on a guppy or danio-sized companion. Best to keep at least eight or more fish in a group.
Hump-headed Blenny
Blennies of the family Blenniidae are small, scaleless, mostly bottom-dwelling marine fish. Over 300 species in various colors can differ between males and females of the same species. They are distributed worldwide in tropical and warm temperate waters. They are occasionally found in brackish and freshwater. Blennies are typically seen in tide pools or peering from crevices and holes in coral reefs. Many species are highly territorial.

Some species can jump between rock pools. Blennies are often confused with gobies that also dwell on the bottom.
However, blennies have one long dorsal fin, while gobies have two. Blennies tend to back into their holes tail first, whereas gobies like to enter head first.
Blennies can be divided into two groups, the bottom dwellers and the free swimmers. Bottom dwellers typically have blunt heads and feed primarily on algae and detritus that they scrape from rocks with their wide mouths and comb like teeth.
Conclusion
Fish with big foreheads have many types that have different colors and variety. We can have some of these fishes in our houses as pets. We can keep these fishes in our homes in glassfish. These fishes may also feed on small invertebrates. Blennies lack swim bladders; hence they sink as soon as they stop moving. Outside of their hidey holes, they usually rest on rocks or corals.
