Accidental Breeding?

[Tempestuousfury]

Very often I see people on here posting about how "My cories laid eggs!" I take it that usually these are unexpected spawns (mainly due to the existence of the "!" along with the fact that if the spawn was expected, research would no doubt have been conducted before the corydoras produced that spawn). Therefore, I would like to know if it is a common occurrence for corydoras to breed without having to tweak the water condition (since I have varied water changes, gone on frozen food binges, etc. to no avail, though this was never really meant to induce spawning).

with my last setup my corries used to spawn fairly regualry, all i used to feed them on was sinking pellets and no live or frozen food. The main thing that triggers them is big water changes.

how many do you have and what type?

 

[Tempestuousfury]

4 albinos, 3 schwartz's. Therefore, I would think that there would be some breeding going on.

And sometimes I don't do water changes for weeks at a time, with roughly 30-50%% changes to undo some of the damage caused by my laziness. Usually it's weekly 20% changes, though.

can u tell if u defiantly have any females? the females generally are bigger than the males. Maybe they have spawned but the eggs have been eaten by other tank mates

I would think that I owuld have noticed a few eggs before they were all eaten. As for there being bigger ones, two of the schwartz's look very big, though these are the less active cories. The two older albinos generally sim along the glass chasing each other, and since I highly doubt that fish have the capacity to have have fun, I was under the impression that perhaps it was mating.

And I have not really seen anything that resembled cleaning off a site for eggs either.

If the conditions are right and you feed them a healthy diet, then they will probably spawn. Bronze and Albino C. Aeneus are probably the easiest cory to get to spawn. What are you feeding them? They are apparently happy with their surroundings. Odds are they will spawn for you again very soon. Mine spawn all the time and I dont do anything to encourage them to do so.

You say "spawn again", but they have never spawned.

As for what I feed them: shrimp pellets daily, blood worms every other day or so, and I drop in algae wafers from time to time. I found my small container of dried tubifex worms... I cuold probably feed this, too, though none of my fish liked it, and it tends to float, so I don't really know how to get it to sink.

oops I misread that post

As for the tubifex, I would not too much worry about feedinf the cories it if your other fish dont like it. All my fish like the tubifex and I feed them the cubes. I just take the cube and rub it in the water and it breaks up and some of it sinks to the bottom.

I had an accidental spawning this morning, it was totaly unexpected! But i think i know why now, i had to unplug their heater a few days ago as i have limited plug sockets and needed one for a hospital tank.. and i did a big waterchange.
My fish are small too. I have three 1-1.5" Bronze cories in a 5 gallon tank. I've had the fish since November 05, so not very old either.

in turning the heater off and changing the water you have done to main things that trigger spawning in corrys.

My tanks have been running without a filter for months, and I do anywhere from 25-50% water changes weekly, depending on how long I have gone without scraping algae. Nothing happened yet. However, I am planning on adding more albino cories, just for the heck of it, so I might get something... hopefully.
