All Fishes Data Sheet
Scientific Name	**Hoplisoma simile** Hieronimus, 1991
Common Names	Smudge Spot Cory Halvplettet Pansermalle (Denmark), Violet Cory, Violetta Cory
Type Locality	Tributary of Rio Madeira, vicinity of city of Ariqumes, Rondonia State, Brazil.
Synonym(s)	Corydoras similis
Pronunciation	hop lee so mah - sim ill iss
Etymology	Latin similis = like alluding to the similarity of the colouration of this species to Corydoras ourastigma.
Species Information
Size	38mm or 1.5" SL. Find near, nearer or same sized spp.
Identification	C. similis is the round nosed ''version'' of the long snouted C. ourastigma. The smudged marking at the base of the caudal fin separates it from other head-spotted species that have a distinct spot marking instead.
Sexing	Female is fuller (when viewed from above) and larger.
Habitat Information
Distribution	South America: Madeira River basin. Amazon, Middle Amazon (Solimoes), Madeira (click on these areas to find other species found there) Amazon, Middle Amazon (Solimoes), Madeira, Jamari (click on these areas to find other species found there) Login to view the map.
IUCN Red List Category	Not Evaluated
pH	5.6 - 7.0
Temperature	21.0-27.0°C or 69.8-80.6°F (Show species within this range)
Husbandry Information
Feeding	Flake, tablets. Live food such as whiteworm, bloodworm, brineshrimp and tubifex (sparingly). Frozen bloodworm is more easily supplied and seems to bring on growth in sub-adults very satisfactorily. User data.
Furniture	Other similar Corydoras, dwarf cichlids and tetras. A robust species that will adapt to larger peaceful tankmates.
Compatibility	A perfect citizen.
Suggested Tankmates	Ideally keep with dwarf cichlids and tetras. A robust species that will adapt to larger peaceful tankmates. Keep in groups of at least six.
Breeding	1. A ratio of 2:1 males to females has been successful at a pH of 7.2 and water at 76F which was reduced by approximately 5-6 degrees the day before spawning took place. It was back up to 76 when they began to spawn. 2. The spawning followed the typical ' T ' mating clinch, where the female nuzzles into the side of the male at a point just behind the pectoral fin. The male then clamps the female by her barbels (hence the need for good barbels, poor barbels means poor grip and possibly poor fertilization). Once the grip is complete both fish seemed to tremble for a few seconds, during this time the female deposited two 1.8mm eggs into a pouch made by clamping her ventral fins together. The female then broke away from the male and proceeded to find a suitable place to deposit her eggs. Altogether 28 moderately sticky eggs (out of a scale of 1 to 10 the these were 3) were laid all on the tank sides, all at various levels. 3. All the eggs were fertile and hatched in 4 days. 2 days after hatching the fry were free swimming and given pre-soaked powdered flake. This was followed by alternate small feedings of either brine shrimp or micro worm. 4. Fry Development is pictured above. The fry grew rapidly and at 7 days were 6.2 mm, at 14 days 9.0 mm, in 1 month 12 mm, after 2 months 16.4 mm, and after three months 21.0 mm. Adult colouration in 10 weeks. 5. After the spawning was complete the adult fish were removed, and the water treated with a few drops of methylene blue (1 drop per gal) to protect the eggs from fungal attack. Once the fry had hatched the water was changed at a rate of about 20% per day, for 5 days, removing the methylene blue concentration.
