Rare Fish's Rare Fish of the Day!

We’ll kick day #6 off with a Nano fresh, brackish, and saltwater blenny!

Day #6 (11/10/21

Top Hat Blenny
Omobranchus fasciolatoceps

View attachment 147543

Size: rarely exceed 2.5”
pH: 7.0-8.5
Tank size (in gallons): 20g
Country of origin: Southern Japan, Hong Kong, and Taiwan
Diet: Insects and Crustaceans (a micro-predator). In captivity, they will accept most frozen food
Temperament: Peaceful but territorial
Nitrate: <30ppm
Salinity: 0-20 (does best in 0-15)
Fished for: No
Status: Least Concern
Harmful to humans: Harmless

Description:

This is one of the few species of Combtooth Blenny that inhabit fish and brackish water. They inhabit estuaries and mangrove forests, but most are collected in slightly brackish to freshwater areas. There have been a few records of breeding. They are substrate spawners, and larvae are planktonic. Read about the breeding on my first recourse. They are often marketed as ‘freshwater blennies’. These fish are hardy, and will survive through tough shipments, cold temperatures, and more.

Where you can find them:
As always, aqua-imports has them. Specialty saltwater stores may have them, but those will be collected in fully saltwater or high brackish areas.

Recourses:

They’re really cute 🥰
 
Any small (under 2”/50mm) fish that live in very hard water? There’s a lot of us would welcome suggestions as there’s been a few lists posted when liquid rock newbies start asking for suggestions.
 
@itiwhetu ‘s guess was quite close. But it was not that fish. This is a true monster fish that I don’t expect anybody to keep besides people who want to spend 100’s of thousands of dollars on fish. Ladies and gentlemen and everybody in between, I present to you, the Aripaima Gigas!

Day #8 (11/12/21)

Aripaima (Pirarucu)

Size: Doesn’t normally exceed 7 feet in captivity
pH: 6.0-6.7
Tank size (in gallons): pffffff take a guess!
Country of origin: Bolivia, Brazil, Guyana, Peru. However, in Bolivia, they are considered an invasive species
Diet: Will accept frozen, can be weaned on pellets (but don’t count on it). They are fish eaters and should be fed a large amount of fish.
Temperament: Peaceful to fish not able to fit in its mouth
Nitrate: <30ppm
Salinity: N/A
Fished for: Yes
Status: Data Deficiency - last assessed in 1996
Harmful to humans: Harmless (unless hungry 😈)

Description:

Originally thought to be the only species in its genus, aripaima gigas is a true River monster. They normally reside in the Amazon River Basin. There are 5 species of Aripaima, only 2 of which are kept. These fish need to be kept on a diet of frozen fish. Some states need permits to keep such fish.

Where you can find them:

As always, aqua-imports has them. Specialty saltwater stores may have them, but those will be collected in fully saltwater or high brackish areas.

Recourses:

 
This may not be a very rare or odd fish, but I like this fish and I would want to keep one at a point in time. Sorry my fish profiles have decreased in quality. Haven’t had much time.

Paradise Fish
Macropodus opercularis

Size: normally not more than 2”
pH: any. These fish are very hardy. Normally in between 6.5-8.2
Tank size (in gallons): pffffff take a guess!
Country of origin: East Asia. Found in cold and warm water with dense vegetation. Commonly found in rice fields.
Diet: Frozen mosquito larvae, brine shrimp, and can be fed commercial flakes
Temperament: Males are aggressive
Nitrate: <30ppm
Salinity: Some reports of paradise fish in slightly brackish water.
Fished for: No
Status: Least Concern
Harmful to humans: Harmless

Description:

These fish are quite common in the aquarium trade. They can be found in cold and hot water. Ponds and tanks. They need/enjoy plants. Males are aggressive. There is an albino variant. These fish are very helpful to humans, because they eat mosquito larvae. In Taiwan, there habitat is being destroyed, and infection of Dengue Fever and Yellow Fever have gone up. These fish are very very hardy.

Where to find them:
Most pond shops will have them
