Cat-eLog Data Sheet
Scientific Name	**Hoplisoma adolfoi** (Burgess, 1982)
Common Names	Adolfo's Cory Orangepandet Pansermalle (Denmark), Panzerwels (Germany)
Type Locality	Small tributary of the upper Rio Negro on the equator near São Gabriel da Cachoeira, Brazil.
Pronunciation	hop lee so mah - add OLL foy
Etymology	Named in honour of Adolfo Schwartz, fish collector.
Articles	- CotM 1998 September
Species Information
Size	57mm or 2.2" SL. Find near, nearer or same sized spp.
Identification	Similar to C. burgessi but has an orange rather than golden head cap and clear dorsal fin. Similar to C. imitator but has a rounded rather than pointed snout. Very similar to C. duplicareus but has a thinner black back stripe. According to the description C. duplicareus has serrations on the posterior edge of the pectoral fin spine, whereas C. adolfoi does not. This, of course, is not easy to see in a normal aquarium. The best way to see if your fish have these serrations would be to place them into a shallow, preferably white, container and shine a light up from underneath. Then with the aid of a magnifying glass you should be able to see if there are any serrations or not. As a general rule C. duplicareus tends to be a little stockier than C. adolfoi and the black band is usually a little broader.
Sexing	Female is fuller (when viewed from above) and larger.

IUCN Red List Category	Not Evaluated
pH	5.6 - 7.0
Temperature	20.0-26.0°C or 68-78.8°F (Show species within this range)
Other Parameters	Slightly soft, black water is preferred.
Husbandry Information
Feeding	Sinking pellets and bloodworm for adults. User data.
Furniture	Dense planting around the edges of the tank, thus providing a large swimming space. Although gravel can be used it is best to use a soft sandy substrate.
Compatibility	A perfect citizen.
Suggested Tankmates	Lots of other C. adolfoi! Being light in colour, this fish looks striking if kept with darker coloured fish. Small South American Characins, such as black neon or black phantom tetras. Large shoals of small mid-water fish will encourage this fish into view.
Breeding	Set-up in a 10 gallon tank with pH6.2 with a low TDS reading. Temperature range of 68°F – 70°F (20°C – 2°C) for best results. Given an adult group of at least 6 fish (a ratio of 4 and 4 to 3 males to 1 female will work), regular water changes and good diet are the prerequisites for spawning. Around 20-30 eggs are produced in clutches over up to 48 hours. They are carried by the female in a ''pouch'' formed by her pelvic fins to the underside of broad leaves or the aquarium glass and deposited carefully. Although relatively easy to trigger spawning, rearing fry appears more problematic. Attention to water quality is essential and some breeders maintain that this species must be raised with its parents or other Corydoras fry in order to learn to eat prepared foods.
