Unhappy Platy fry keep dying - help!


I have a bit of problem with my Platy babies and need advice!

A few months ago I noticed that my platies and mollies had fry, i managed to salvage about 9 of them and put them all into a breeding trap in the main tank. The breeding trap is just a seperate plastic compartment with small holes so the adults cant get to them.
I was feeding them powdered up tropical fish flakes every day and they seemed happy and healthy until one morning I woke up and they were all unexplainably lying dead in the bottom of the breeding trap! I can't seem to be able to think of a reason for this as none of them were acting different and they were all lively and healthy. They were probably about a month old and growing well etc.

And again recently I rescued about 8 more Platy fry, and the same thing happened after about 3 weeks.

I dont know why this is happening! I have managed to successfully raise Guppy fry before though I understand they are somewhat 'easy' to raise.

If anybody can please advise and possibly give me an explaination as to why this is happening that would be great. Thanks!

do you have a kit to test your water's parameters? i wonder if you had an ammonia spike or something like that.

It is definitely water quality.

there could be one of two things from my experience.

1) the bad water quality in the breeder, i always try to clean up their waste everyday with a syringe with a piece of vacuum line attached to the end ( basically a mini gravel vaccum for the little floating breeder things). It could have just got to a level too high and too quickly and killed them.

2) Did you just do a large water change the day before? I had a Platy fry tank with LOADS of young platies cause i breed them. I got very busy with work and school over a week and a half and didnt do my water changes that i should for a tank with that many young fish. BUT they were all doing well it seemed, cause i didnt see any of them showing signs of poor water quality. So when i got a chance a week and a half later, i figured i would do a larger water change to make up for the week i sadly neglected their water change. Within literally hours they were all dying off left and right. I did an emergency transfer to another tank to save as many as i could but what happened was they had become accustomed to the water because the levels were rising slowly enough they could adjust and not get sick. SO when i did a large water change, the clean water wasnt what they were used to and they were shocked and died quickly especially since they were so young bad experience but its another lesson learned

I have raised Cory fry in a filter box which I hung inside the tank to keep the temp. constant, I changed about half the water every other day and removed the detritus from the bottom, fed them well but not a lot result lots of baby corys which I later released-to grow to adults. I guess what I am saying is watch your water parameters and try not to shock you fry with major water changes. Consistency is important with all fish but especially young fry!!!

The breeding trap needs to have water exchanged thru it everyday,
The water does not circulate thru it and can turn bad rather quickly.

Raise the trap everyday and let about 3/4 pour out thru the holes, then lower it back into the tank to refill with new water from the main tank...

This is a common problem many people fail to do and the end result is dead fry/Fish.

Always in NEED & looking for more Tanks!

I put a small bubble stone in my breeder trap which keeps the water circulating also pulling in fresh water. Along with that I use a turkey baster to suck up uneaten food keeping the bottom clean.
