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.
Those are awesome photos of the laying in action! Mine spawn when I do a cold water change. So far I haven't been able to keep any to try and hatch them out but from what I've heard corys are fairly easy to hatch and raise. An egg tumbler helps.
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!
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.
