A rare fish is a fish that few people in your area keep. And for various reasons. or restrictions...What is a rare fish?
is it rare because its hard to get in a LFS?
Is it rare because it is only found in some remote creek or lake in Timbucktoo?
Is it rare because the counrty it comes from doesn´t allow fish to be exported? such as Madagascar...
It is rare in El Paso but not in Greenbay?
Is it rare because in won´t spawn in a tank?
It it rare because of politics? (Nandopsis ramsdeni from a remote section of Cuba,
or Iranocichla hormusensis from the straits of Hormuz?






In my country, fish which is rare in nature means that it is protected species. So if you keep it in aquarium, you are asking for an unnecessary problem.To me a rare fish needs to be not only rare in aquariums, but be rare in nature..... for instance,
only be endemic to a tiny area in nature, such as a singe lake, pool of stream.
Oreochromis alcalicas is only endemic to a desert, soda lake (Natron), more saline than th ocean, and reaches water temps of above 100¨F.

Coptodon bythobates is only endemic to a Crater Lake (Bermin), and has enhanced hemogloblin that allowsit to survive hydrgen sufide burps that cause low oxygen.

The red color signifies enhanced hemoglobin.
One area I find interesting is the bridge created in Panama where S American species migrated north.
Cichlids restricted to only rivers east of the Mamoni to the Darien, are found there.
To get them, I had to move to Panama to catch them in nature 10 years ago.

Darienheros top, a Central American eartheater, and Geophagus crassilabrus(lower fish), the only Geophagine eatheater, that migrated north into Central America.
It could be botia helodes,very agressive type of loach.This guy is at least uncommon in my area. He was sold to me as a one inch Berdmorei Tiger Loach.
His color markings are substantially different than an adult Berdmorei Tiger I currently keep and had raised from a juvenile.
The general concensus of several fellow Loach keepers has been, he's likely a Berdmorei harvested from a different waterway than my adult Berdmorei.
Whatever species he turns out to be, he's a fast growing brute.
