how could i tell the difference between a female and a male spotted cory catfish or any cory catfish for that matter? and i was also wondering why my little cory catfish(who is spotted) doesnt really swim around in the tank with the other fish. my other catfish have all schooled up together and i was wondering if its because they are alike and the spotted one doesnt look the same. he just seems really lazy to me. he sits in one corner of the fish tank and donest move what so ever. he just sits there and literally does nothing. he only gets active or acts happy when he knows when its feeding time. and the other cory catfish (the ones that are albino) are active all the time and seem really happy to be in the tank and are happy with swimming with the other fish. so if anyone could tell me whats up with my lil guy would be great and also tell me how to tell the difference between a male and a female, and why my lil guy hasnt grouped up with the other cory catfish. thanks. ((also im going to be purchasing a few more spotted cory catfish so my lil guy has someone to group with and hopefully if i do that he will at least be a little bit more active inside the tank along with the other spotted corys))

Usually the different species of corys will not school together. You should definitely get your loner some buddies.
As for telling the sexes apart I was unable to find a method for doing so unless you see them actively spawning. Sorry.

thats fine. i was just wondering. and my little loner guy just seems very inactive for being soo young. my other little baby albinos are whipping from one end of the tank to the other. its just strange how the two different species are acting soo different.

I have an OLD fish book called "Enjoy your catfish" that I got "way back when." There's no publishing date, but it's by the PET LIBRARY; ENJOY series (I got it in the mid-late '70s). It's by Albert J. Klee, and is 32 pages long; page 27 has outline drawings of both male and female Corydoras, and Loricaria, when viewed from above. In case you can't find a copy anywhere the males are wider in front of the pectoral fins, and the females "at" (or just behind) the pectorals. This is the book that introduced me to Corydoras schwartzi (page 5); it's a very basic book but has some good photos. It's not in this book, but Corydoras barbatus are sexually dimorphic (I wish I could find some somewhere, but then I probably couldn't afford them), and there are pictures of them in various Corydoras/Catfish books. One of the books I have says they have been called Scleromystax barbatus at times (this was in a book copyrighted in 1997). I really wish I could get some more recent books.
I'm having trouble getting cories. I've had some (not the common paleatus, aeneus, etc.) on order for over 4 months. The last time I got any (last fall) there were only 2 of the same species (I got lucky in the fact that they were schwartzis) in the tank. When I got them, they were being sold as "spotted cories" (that specific species is not available to order for some reason), and when I placed my original order for "spotted cories" it took over a month for Petco to get them in--and they turned out to be C. paleatus! So I tried again and they've ordered them as both "assorted cories" and C. agassizii (as well as a couple others, that I can't remember). Even this way I've been waiting forever.

I've noticed over the past couple of years that Corydoras have become one of the most popular fish at the LFS around here. Demand must really be going up.

Greetings All, I just spotted this thread.......It is very hard to tell the difference in the sexes of cory cats when they are young - but as they get older, the females will have a larger, rounder body (females generally get bigger than the males). I don't know if this is true for all varieties....I can tell that some of mine of female and some are male. Cory cats of mixed varieties will eventually school together. I am particularly fond of cory cats and can't have three or more of a kind in my smaller tanks (I just like so many of them!). I have a two gallon Betta tank and there is a young Elegans and a young Panda (both will move to a larger tank when they out grow this one). My ten gallon quarantine tank has two Julii, one Elegans and one Agazzi (the Julii and Elagans stay.... the Agazzi gets moved when he/she grows up a bit. Both of the Julii are females - not sure about the Elegans)- and they all hang out together. I recently added a reticulated cory to my 20 gallon high (before I knew I had the worms infestation -- see my other post in disease/illnesses about that). The new reticulated cory is a loner right now, but I can't add any friends for him yet. I have a large reticulated in my 75 gallon and two sodalis (which are very similar) that do hang out together. This new little guy is too small for the 75 gallon. Hopefully the worm treatment won't kill the young cory and he can be moved when he grows up a bit. I have raised many cory cats in the smaller tanks. Each group of cory cats has their own territory in the 75 gallon. It is so much fun to watch them. On occasion, the Emeralds hold a Cory Cat Convention and invite them all to the Emerald City (the back right corner is their territory). Right now, I am looking for hi-fin albinos and Robinae (flag-tail cory). I lost Princess 1 and Princess 2 recently(my hi-fin albinos)...and passed up buying the Robinae when I saw them as they were already full grown. I haven't seen them since. Since I don't even plan to breed fish, sex of these isn't important...."Googling" - sexing corydoras - brings up some helpful links (and some not so helpful -- smile). Here are two that are helpful: www.planetcatfish.com/forum/viewtopic.php?t=6875www.scotcat.com/articles/article33.htmJudy D.
