Species Information
Size	61mm or 2.4" SL. Find near, nearer or same sized spp.
Identification	Probably the most misidentified fish commonly found in aquatic retailers who incorrectly sell it as C. julii. The true C. julii is such a rare import that sheer numbers mean you are unlikely to really encounter this Brazilian fish. C. julii is similar to the more spotted forms of C. trilineatus but has no trace of any reticulated colour patterning at all and is entirely covered with small, distinct spots. It's mid-lateral black stripe is fainter and does not reach as far towards the fishes head as in C. trilineatus. This species was described in 1872 with a couple of paragraphs of text and drawings which do not clearly show coloration. The author notes, "Light straw-colored, brownish above, a yellowish lateral band with rather faint brown margin above and below, and blackish median line. A very black spot on the ends of the soft dorsal rays; tail deeply forked, with five vertical bands; anal spotted. Some longitudinal lines on the side of the face".
Sexing	Females grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.

IUCN Red List Category	Not Evaluated
pH	5.8 - 7.2
Temperature	16.0-25.0°C or 60.8-77°F (Show species within this range)
Other Parameters	A hardy species that will tolerate most water conditions found within a reasonably maintained aquarium.
Husbandry Information
Feeding	Sinking pellets and frozen bloodworm are ideal although all prepared foods that reach the bottom are accepted. User data.
Furniture	Sandy or small rounded gravel is required to ensure the fishes barbels are not damaged in the search for food. Some plants should be used to provide shade and a sense of security.
Compatibility	This commonly encountered Corydoras is a perfect community tank citizen.
Suggested Tankmates	Should be kept in a shoal of at least six individuals. This, along with the presence of some mid water shoaling species, will increase the confidence of the fish in a community tank environment.
Breeding	The fish appears to prefer clean, soft water and should be conditioned in such an environment. pH and temperature seem less important but a drop in temperature may induce spawning. The eggs hatch after four to five days. The eggs are very susceptible to fungus and best removed, treated and the fry allow to hatch in a very controlled environment. The young can be raised on newly hatched brineshrimp again vigilance in respect of water quality is paramount.
