SENEGAL BICHIR fry disappearing/dying at 1cm size

Sorry to hear that mate. At least yours keep laying eggs. My breeding tank randomly cracked and I had to put my senegals back in my main setup until I can replace it so I only have the fry from this batch for now. I wanted to ask what temperature do you set your breeding tank to when you are trying to get your sens to lay eggs? I am also going to buy some of those aqua one grassy mats once I replace the breeding tank. Hopefully you get some more time and have better luck next time you try collecting the eggs. Who knows maybe a few random baby's will survive in the adults tank lol.
Nice to hear the fry are eating.
Is this true? I wouldn't expect it to be the case in nature? I mean they are tough fish so I would expect their lungs would develop as they age and start breathing at the surface. I wasn't planning on doing this and plan to see if my fry develop fine or not. They are around 7mm at this time. Guess I will find out if mine make it past the 1cm mark. Lets hope. Not doing too badly at this point for my first attempt at raising fry. I think around 15 - 30 are alive at this point. Many are exploring and swimming around the tank. I had less sucess raising fancy guppy fry lmao. That was my only other attempt at raising any fry before these sens.
I'm just going off what I read on the forums in regards to water parameters. To be honest I am just sticking to the suggested temperatures and performing regular water changes from a grow out tank nearby. I change the grow out tank's water then once it reaches optimal temp again I then do a 70 percent water change to the fry tank. I am very cautious about vacuuming the bottom of the fry tank at this time also as I don't want to risk fry getting sucked up and hurt. The fry tank is around 20 litres or so. I also have a small powerhead sponge filer with the intakes covered by netting to prevent fry getting sucked in and also a uv sterilizer on the output. I run this from time to time to suck out old microworms etc. I also have a sponge filter and aerator with airstone. I haven't been using the uv sterilizer filer much lately as it was more to try to mitigate fungus on eggs.
The moist layer is important, remember where they live is more humid and polypterus are particularly reliant on their lungs...
Just something I read awhile back. "Our" air is more conditioned in our houses then in their natural habitat. So the reason for the glass top would be two fold stop them from jumping and stop the water from evaporating and trapping it in a confined space that the bichirs can draw air from. Nice and humid just like home. Do I know its 100% needed or true no. But there is a fact on mud puppies/ tiger salamander larva that they need a warm humid area to help in the transformation, not so different.
Have you tried again or had any success raising your fry? I currently have 3 fry on the go that I believe will survive. Two have made it past the 1cm mark.
