That is really cool! I was thinking of trying to breed some cories. Can you tell me how you did this? Tank size, water parameters, any other inhabitants? Have you ever had them lay eggs before?

They're in a planted 40b. (diy lighting 23 PAR @ substrate, heavily planted, no CO2) There are 7 in there (I have 8, but one is in QT because there's something up with his eye.) I got them from a fellow board member who suddenly found himself in unfortunate circumstances and needed to clear out tanks/plants/fish. Their only tankmate is a female bolivian ram hat came from the same user. I have my h2o params in a log in the fish room, I'll have to get back to you on that.

These guys are fairly new to me (I picked them up from their previous home on 8/17,) so no, they've never spawned for me before.

Their spawning may also be attributed to the weather we've been having. The past few days have been stormy (some really crazy t-storms in the early morning hours Sunday) I'm noting the current barometric pressure at 1009 mb but will be going back to look at the past 48 hrs of logs.. I'm very interested in the effects of atmospheric pressure on a fishes inclination to spawn.

Holy gigantic photos, batman. Maybe cut those things down to size before uploading?
I uploaded from my photo software to my server.. They've already been cut down a bit :p

I figure since they don't get hosted here, why not leave em big. (Especially since they auto resize in the forum.)

If its a big deal I can resize.


There's nothing cooler than baby Cories!
I'm excited! It's my first time keeping cories in about 10 years and my first time rearing them.

Awesome. Mine in my 20 gallon lay eggs almost every month. The eggs end up white and fuzzy and have to be removed. They just laid again a few days ago and no fuzziness yet. It's weird watching them as the females sort of tbone the male to get the good stuff

there is a big link in egg layers spawing and low pressure fronts. most of the cory people i know do large water changes with water that is a few degrees cooler when storm fronts move in to induce spawing. works with all kinds of fish. ive done it with guppies and rainbows as well. angel breeders and cory breeders do it alot as well.

My green cories usually get triggered to spawn when I do a water change with slightly cooler water. In the past it's also worked for me if I raise the temperature up to about 76 degrees and then unplug the heater so it slowly cools down the water. Of course you have to have a female fat and ready to lay eggs. =D

Grats Olive on another successful spawn! You will be RACKING up the BAP!

Awww, they're so cute being all romantic.

Meanwhile in space.....alien posts on The Planted Earth forum...."So, I caught my Caucasians spawning and got pics!!!" and everyone responds with excitement, asking how they did it and what parameters they had.

Not so much a server issue but end-user issue. Images that are slow to load (even on broadband) just end up getting ignored by folks.

I try to keep my images under 2K pixels wide for the sake of easier loading. Often, I'll just cut things all the way down to 640 wide unless lots of detail is needed.

Either way, cool pictures of Cory eggs!

When our albinos spawned in our 46 gal, since it is a community tank with all sorts of fish, we used a cup and plucked out out as many eggs as we into the cup and transfered them into a 10 gallon ghost shrimp tank we have set up with a sponge filter we literally put the eggs right next to the sponge filter on the glass and a few days later a bunch hatched we ended up with about 8-9 more corys, we had only found 12 or so eggs to move over I do believe the other fish in the community tank gobbled down a bunch before we spotted them we love corys and have 6-7 different kinds they are such happy little fish

Also... Please post photos of the eggs as they develop!

I love watching that kind of progression.
I need to get some shots of the eggs today, they'll be hatching soon.. I might steal my BFs 5d and try to get video..

I'm currently raising lots of fry (2 T. Ocellicauda spawns and ongoing hatchings of I. Werneri) so I have lots of tank space already devoted to little ones. The eggs have mostly been removed (either via scraping from glass or leaf removal.)
