Corydoras Bilineatus - San Juan Cory

I just purchased a group of 6 Corydoras Bilineatus. The LFS atated taht they were last seen about 3 years ago. The data on this site did not have much other than the scientific name.
I'd like to know more about:
- Size,
Water Quality requirements (some cories like more alkaline water than others),
Natural habitat,
differences to typical cories (if any),
breeding (cories in general)
Thanks,
Scott

beersnob,
This is what I have.
http://www.corydoras.myby.co.uk/corydor ... neatus.htm
They grow to about 2" (50.0 mm) and are related to C. elegans, they spawn in typical Cory 'T' fashion. Eggs are very small (.75 mm Dia). Water conditions are not critical, temperature around 76º F.

Ian,
As expected, you provided me with a wealth of knowledge.
As a continuation of this topic, I have 5 different species of Cories (total number of fish is 5) that shoal together. Is this acceptable to breed the different Cory subspecies? Or is that not possible due to small changes in the biology? Furthermore, how is the male differentiated from the female. I have read about Female Corys looking like tugboats, and Male Corys looking like sppedboats. My problem is that I see them as all stocky and was wondering if there is a body feature that would assist me in this determiantion?
Again, I need to further look at the information you have sent me and if it is located in that information, just say "look at the info" and that would be great!
Thanks for your assistance!

What about Aquarium size for the spawning? Is a 10 gallon appropriate? Would a 20-gallon do the job mote efficiently?
Thanks,
Scott

Hey Scott,
Please don't try to hybridize the corys, some interesting things could turn up but this just causes a real mess later. Just look at all the trouble that people who are into Lake Malawi cich lids are having w/ hybrids, it's about impossible to correctly ID most fish sold out of average fish shops these days.
This is also the reason you're having trouble telling males from females, you need several of the same species to compare to eachother. Once they've bulked up a bit after being in your tank a while the differences are quite easy to see from above. The females will be thicker in the middle of the body while the males will be more tapered. And also a 10g should be fine for spawning, since there will be only 3 fish in it until they're done. This also makes feeding & water changes easier.
Anyway I wish you well with your bilineatus, I just bought 7 last week myself a little further up the state. And of course once they fatten up a bit I'll be trying to spawn mine too, good luck!

I just caught where you're at! Saginaw, oh Saginaw! Not so far from the Bay City area! A very good Brewpub exists there that allows you to cook your own steak! (I'm not mentioning names on the site!)
Thanks for the info! It's nice to see there are many Michiganders here on the site! I was really impressed by the darker colorations than the "typical cories" you see at the LFS!
Later,
Scott
