Krib Eggs In The Open.

I looked in on my Krib tank earlier and noticed they have spawned again, this is their third lot.
What interested me this time was they laid the eggs on a piece of bg wood in the open and not in a cave where from what I've read they normally do lay.
I was wondering if it is because they don't feel as threatened in there seeing as they are on their own with about 5-6 of their last litter and no other fish to really worry about?

Out of Interest there is around 50-60 eggs and they appear to be moving slightly so not far off hatching.

Hi Sue,

Well the first lot of fry they had in a community tank and bit by bit they got picked off by the other fish even though the parents did their best to guard them, I managed to save 8 and I put them in a small 24 liter tank by themselves, I have rehomed 4 of them and I have a fish shop that will give me credit for them when they get bigger.

So I moved them to another tank with 5 x Danio as dither fish, they spawned and had about 70 fry, so I removed the Danio and left the Kribs by themselves, I decided to let nature take it's course and I would see what happens next, they were great parents and the fry followed them around as normal.
Then I noticed that the fry seemed to be missing, I could spot about 6 and no more, I searched online and I read that sometimes if the male wants to spawn again he can eat the fry, so I am presuming this is what happened, so there is about 6 of the second spawn but they are still small.
I think I will try and net the remaining fry out and put them with the first spawn, if I can catch them lol.

Something very strange is going on!

I looked at the Kribs last night and all the eggs had gone but...  The male was guarding a cave that the female was in, I presumed they had moved the eggs or they had hatched and they took them in there or eaten them.

This morning I looked and the same thing the male guarding the cave,  I thought I would do a small water change on that tank, got the gear ready and...  Got a shock,  they had laid another batch of eggs on the bog wood or they had moved them again, this time there didn't seem as many but still a lot, possibly 50 eggs.

I still did the water change making sure I kept to the other end of the tank, I thought some fresh water will do no harm any way but I didn't do a gravel vac so as not to disturb them any more.

Well update:

I'm baffled now, I had a look not long ago and I got another shock, the eggs are back on the bogwood!
There seems to be around 80+ eggs, the male is guarding them but the female in busy to a fro between 2 caves, sometimes she visits the pile of eggs on the bogwood and the male goes in the caves, then he returns and she goes in the caves, first one then the other.

I am now wondering if they have gone overboard and got 2 or 3 spawns going at once.
