CALVUS FRYE... HELP

[Italian1026]

I have a pair of BLACK CALVUS that breed on a regular basis, prob like once ever 5 or 6 weeks. I have tried a few diff ways to keep the frye alive and no LUCK. The first time i tried is leaving the frye stay in the cave till they can swim and they escape out but they end up getting eaten. I also have tried to take the frye out put them in a specimen container ( hang on container ) with an air stone with the same water thats in the tank they were born in and they live a week or two and a few die off each day. Then I tried to put them in a container again and add a few drops of Aquari-sol and well they keep dying off each day. They sit in the container and they dont really move around, i see them eating but they dont swim around much unless somethign scares them. I feed them microworms and decapsulated brine shrimp eggs. But they tend to go after the microworms, i think they see it moving so they go for it..
I had a batch of 104 frye and a batch of 113 frye and as of now i got 1 LEFT from the first batch and 7 left from the 2nd batch. I have this tank in the garage but the tanks water stays around 76-78 in there..

So can someone out there give me any ideas of what i am doing wrong here or any suggestions on how to keep these fish alive...?????????????????????? plz HELP

Hello, I'm Mihajlo from Serbia.

Friend has 9 adults calvus and also had difficulty with raising the young, as from 4 spawn raise only 15 young fish.
He brought me shell with 10 liters of water 9.11.2008. I put in my small aquarium of 11 liters. Temperature varies from 25 to 27 degrees Celsius, because I do not have a heater. Lighting the bulb of 25w. In aquarium only filter sponge, and two stone.
All the juvenile came out from the shells after three days. I have given them live Artemia salina nauplia and microworms, eat them well. But small dry food and frozen water bugs taken in the mouth and spit out out. Only eat live food.
At the beginning the length about 7 mm, and are now 9 to 10 mm long.
The third day 3 fish died, and not any more.
There are about 110 small fish.

I want you more success in the spawn of this beautiful fish

Good luck

thanks for all of you for helping me with this topic. I figured i would give an update on these guys since then i had them spawn a few more times and deff kept them alive. I have since then sold the big pair since they were producing way to much fry for the little amount of tanks i go and just dont have a lot of tanks to grow them all out... so i traded them off for other fish..

thanks again
