Disappeared, which is why I'm inclined to think something ate them.

Well, another spawning occurred yesterday. Total of 28 eggs. Here are some photos taken mid way through. There are two females and one male in this tank, so no idea which female, they look identical to me.

Wow, nice shots! You can see how distended with female's belly is. Does the male then come along and fertilize the eggs?

I observed for almost an hour (fell asleep actually). The female meticulously cleans the glass around the existing eggs, the male periodically comes up from below her, sometimes to her side, there is a bit of twitching of their tails, but I could not see any eggs being deposited. From what I did observe, I believe they deposit and fertilize the eggs simultaneously side by side, in characin fashion as opposed to separately like angelfish.

It's quite fascinating to learn how each species spawn. My Angelfish fry are now free-swimming. I cannot believe they made it this far in a community tank.

Assuming you mean the fish pictured below, Rineloricaria sp. L010A, no, I've never seen them. I have two other Rineloricaria species in the 115g Amazon riverscape. The fish that spawned are Farlowella.

Update--hatching and another round of spawning

This morning I noticed the Farlowella were again spawning; about a dozen eggs so far. At noon I interrupted the proceedings to do the weekly water changes. The water level of course dropped below the egg clusters on the tank wall, but this has occurred previous weeks and I just splash some water over them a few times so they don't dry.

When the tank refill started, I noticed that about half of the oldest (black) eggs were gone, and they had been there when I started the water change. A group of 4 or 5 tetra were also gathered on that side under the eggs. H'm, I suspected you know what, and I was right.

I found 7 hatched fry hanging on the glass (1 on a plant) and managed to net them and move them into the 10g. With all the plants in there, plus the much smaller fish, they may have a better chance. They require soft plant matter and algae for their first feedings once the yolk sac is absorbed and that is the most likely tank for all that. Having hatched, they will now take 5 days to absorb the yolk sac, according to the spawning reports. Then we'll see.

I tried photos, never expecting any luck with my cheap camera, but--surprised again, they are not bad. This is one of the fry. They are about 5/16 of an inch in length.

Byron.
