Golden Basslet
The Golden Basslet, which is not only rare but also difficult to get, is fifth on the list of the most expensive tropical fish. The golden basslet is a species of fish in the Grammatidae family that lives on coral reefs in the Caribbean Sea.
The fish stands out among the basslets because it has a primary color that is not purple. Instead, it is mostly golden yellow with purple patches on its fins and a faint trail on the belly near the fins. The dorsal fin also has a black mark. It is smaller than the Royal gramma, measuring about 7 cm (2.7 in).
This species is thought to be mostly endemic to the waters surrounding Cuba. A solitary specimen, however, has been discovered off the shore of Little Cayman Island in the Cayman Islands. It is unclear whether this is a different population or a displaced person.
This species is popular as an aquarium pet, however, it is not as well known as other species due to its recent discovery. It is noteworthy that it is the first basslet to have a separate color morph produced by enthusiasts, namely the "Platinum" variation, in which the purple coloration is replaced with white coloration.
