Key identification features
- Elongated, stocky body lined with rows of bony plates bearing small backward-pointing spines
- Striped Raphael catfish show bold cream or yellow longitudinal stripes running the length of a dark brown to black body
- Spotted Raphael catfish show white or cream spots scattered over a dark body instead of continuous stripes
- Sharp, lockable spines at the leading edge of the pectoral and dorsal fins, used defensively
- Short barbels around a small, downturned mouth, and a flattened, wedge-shaped head
- Modest adult size, usually 5-8 inches
Common look-alikes
- Spotted Raphael catfish vs striped Raphael catfish: the pattern itself is the giveaway, continuous longitudinal stripes versus scattered rounded spots
- Other small doradid catfish: generally lack the strong bony lateral plate ridge and locking fin spines typical of Raphael catfish
Where you'll see one
Raphael catfish inhabit slow-moving rivers, streams, and seasonally flooded forest waters across the Amazon and Orinoco basins of South America, usually staying near cover such as submerged wood, roots, and leaf litter during the day and becoming more active after dark.
Frequently asked questions
How do I tell a striped Raphael catfish from a spotted Raphael catfish?

What features make a Raphael catfish easy to recognize?
Its rigid, plated body edged with spiny armor and either bold stripes or spots are distinctive enough to separate it from most other small catfish.
