Hey Joe, that fish sure looks familiar!
Here is a section that I wrote about them:
XXXXXXXXXX
XXXXXX
Maximum size: 18 cm
Habitat: Caves in deeper water
Range: XXXXXXXXXXXX
These shy fish tend to prefer to hover in dimly lit caves, waiting for small fish or shrimp to swim by. Completely peaceful with any other fish too large to be swallowed completely, the XXXXXX is often out competed for food by faster, more aggressive tankmates. They also take some time to adapt to aquarium food, so it is best to house them separately until they become accustomed to feeding. Typical of fishes from this region, they do best if kept at temperatures below 70 degrees.
