Name: Corydoras adolfoi
I set up a 90 liter tank for 5 Corydoras adolfoi about a year ago. They require pristine water of pH 6.0-6.5 and very soft because adolfois are generally wild caught. My fish share their tank with 2 whiptails, 2 bolivian rams, 6 head and tail-light tetras and 2 bulldog plec's. They are very shy fish but if I sit and watch the tank for 10 minutes they will come out and play in a group, chasing each other about wildly. I was cleaning out the tank recently and was delighted to find 8 tiny juvenile Cory's under a piece of bogwood! Corydoras adolfoi will breed readily if kept in really pristine water and my youngsters are now thriving in their own 65 liter tank they share with 15 glowlights.
This is possibly Corydoras duplicareus, not C. adolfoi since these species are very similar. Again with this picture the quality only allows a guess at adolfoi as you have it marked.
I also have adolfoi cory, it lives with other corys, platys and male guppies. I have found it's a very beautiful fish that is friendly and hardy. The adolfoi has lived happily through changing water conditions. My tank has a pH of about 7.4 and it is living happy.
Corydoras adolfoi are attractive looking fish, but be aware: they need clean, pristine water. I learned this when I added one to a small tank I'd setup, but because the aquarium water had not matured enough he didn't survive very long. It's better to add them to a clean, but well established tank. Keep them in groups or with other similar marked corydoras.
I have five Corydoras adolfoi in my tank and they are very peace-loving. My 90 cm tank consists of a pair of Apistogramma agasizii, a pair of A. macmasteri, a pair of A. cacatuoides. The Apistogrammas are all breeding, and so are the corys. I have two pairs in my tank with one 'dither' fish, forming a trio. The pair have had their first batch of fry and the trio, their fourth.
I used to have 2 of these fish but after one of them died, the other was very lonely and was always hiding behind the driftwood in the tank. So I picked up 2 more to keep him company and since then, he has been more lively and comes out more often. I recommend to get more than 2 of these guys if you want them in your tank
I keep 2 pairs of Adolfo's in a 75 L heavily planted tank. They share their home with 12 clown killies and 2 Otocinculus catfish. Tank Parameters are pH 6.4, GH 2, no ammonia and about 2-4 ppm Nitrates, Temp about 26°C. The clown killies spawn continously. About once a week I have need to siphon them out and I put them in grow out tanks. As I have only had them for two months, the juvies are still growing out. I have seen my Adolfo's mating. I have a piece of driftwood on the side with about 4 different varities of Anubias as well as a Java Moss bed. They hang out there and I have noticed another curious behavior under the duckweed in the tank. I have seen them rest on the larger pieces of duckweed, and kinda use them as a float to stay near the surface of the water. I am thinking since I feed live and frozen foods that tend to stay in the water column (clowns will not eat off the bottom) and this includes fruit flies and spring tails, I am thinking they want to be where the food is.
