    Following two weeks with no water changes, and a lot of black worms and grindal worms, and 50% water changes yesterday and today (the later change with rain water) my Corydoras C123 are spawning. If you move to about 2 minues in, you'll see two of the fish in the T-position. Sorry for the low quality, but I didn't want to get too close and disturb the spawing.

    From here, the trick is getting the fry from the eggs, and growing out the fry, which is not that easy with this species.

    Probably the only video of this, correct?

    Quite possibly, since I only know of one or two others, both in Europe, who have had this fish spawn. I took another later in the evening and I'll post that later. Probably 150-200 eggs in total.

    They are at it again tonight! About 30 eggs so far. Never had them spawn twice in one season before.

    Wow, Matt; that's great. I wish I had your touch! My 123s just sit there and look at each other.

    Don,

    I have no idea what the triggers are. I hadn't seen these guys since the last spawning. The tank is planted and has a fair amount of wood, and the C123s were staying low, for a month. I did two 50% water changes last weekend, with rainwater, but that didn't seem to do anything.

    I did lower the water level yesterday, for another purpose, but only three inches or so. I've been feeding some Repashy food for the last few weeks, mostly Grub Pie.

    Found at least 100 eggs this morning.

    I've got a bunch growing out from the last spawning (yes, there is one shrimp in there, too:

    The juveniles are coming all nicely. Today, they were mostly hovering in the midwater area, which they hadn't done before.

    Spawned again at some point in the last three days (I've been out of town). No video, obviously. This followed almost two weeks without a water change (just like last time), and heavy feeding of Cobalt pellets, Repashy Fruut Luups, blackworms, and grindal worms.

    Water temperature is 74F and the water is very soft (58 ppm hardness).

    Knowing corydoras, they did this on April 1, just to mess with me.

    Mine did too (on the 28th). Do you suppose they're networking?

    If they're networking, mine are out of telepathic range. Perhaps it's the all-lead aquarium...

    I've been converting some of my tanks to corner mattenfilters, which requires removing all of the water and fish from the tanks, so that you can silicone in the braces. Friday, I removed all of my C123s from their tank. I picked the largest female, who is probably more than 3" long, and two males and put them in 12 gallon tank. The rest of the fish I put in a 30.

    Monday, I did a water change on the 12 gallon tank. Today, I saw a couple of clumps of eggs, and noticed that the trio was still spawning. Tonight, I started removing the eggs, and found about 80 on the glass. Knowing that these fish can put their eggs in strange place, I felt along the back wall of the tank, and found another 40. I then noticed some eggs on the leaves of a crypt that I had thrown in the tank last week, without bothering to plant it in the substrate. I looked at all the leaves, and found lots of eggs. I then pulled out a sword plant, and its leaves had eggs, too.

    I'm guessing 200-300 eggs, all from one female.

    That inspired me to do a water change on the tank that has the other C123s.

    Maybe I need to move my corydoras more often, and also try reverse trios in small tanks more often, too.
