<br>

Has anyone experience this??? whats the survival rates?

<br>

<br>

My first batch, I only had 2 left from 30.

<br>

Now this is my second batch... I have about 40 frys... wanna keep them all alive.

Maybe the plenum discussed at the meeting a few months ago would be worth a try.</DIV><DIV id=Atextbox><P><STRONG>Author: burundi 6 bar</STRONG><BR><BR>10 % a week is far from enough id say,id be doing that on a daily bases till the problem is cured.

<br>

How is tank set up ,whats ya feeding routineand what kind of filtration ru using.

<br>

How long has it been set up do u age your water,the list goes on and on.

<br>

Cheers

</DIV><DIV id=Atextbox><P><STRONG>Author: danceswithdingoes</STRONG><BR><BR>Tony I had this occurring in my fry growout tanks with sponges filters and had (wife had to) to change 10% every second day and rinse the filters alternatively weekly to stop the fry from dying (one a day every day) I reckon that the nitrates were building up quickly due to overfiltration and generous feeding and the weaker fish that were more sensitive to change karked it first. On a positive side the survivors are very hardy

</DIV><DIV id=Atextbox><P><STRONG>Author: Anita ozfish</STRONG><BR><BR>I'd also be looking at what sort of water you are putting into the tank for the water changes. Doing more changes is all well and good as long as it isn't straight from the tap - then you will only make the problem worse

</DIV><DIV id=Atextbox><P><STRONG>Author: DFishkeeper</STRONG><BR><BR>I have found that at about 2-3 mths of age 6 bar Frontosa fry can start getting quite territorial and aggressive towards each other. This can result in the type of losses you are talking about, especially as you say you have them in a 2 ft tank. I counter this problem by moving the fry to a larger tank after 2 mths or so and mixing them with other fry around the same size (eg blue dolphins, taiwan reef) to distract them. This seems to work for me and my losses are now very low.
