My convicts hatched out a batch of new fry yesterday afternoon. I need to get them moved out of their parents' tank and into their own 5 gallon to induce another spawn and to minimize the chance of cannibalism. The fry tank has a HOB filter with fry guard and a brand new substrate consisting of a thin layer of crushed oyster shell for pH buffer and calcium (my water is very soft, with GH at 2-3 dH and no detectable KH).
The same tank until yesterday housed an earlier batch of convicts which grew up ok with a bare bottom, but they didn't seem to grow as fast as I had hoped so I'm trying the shell this time. Those guys are now in a 10 gallon.
My problem is that the turbidity from the new shell hasn't cleared yet. This was chick-grade poultry feed and had a lot of fine dust in it. The filter and normal siltation has cleared it up a fair amount since yesterday, but it still looks like I poured a glass of milk in it. Visibility is pretty good looking sideways through the tank, but end-on you can't see the other side.
Normally I would just wait a few days for it to clear, but I didn't plan this very well (didn't see the eggs until the day they hatched) and now I'm in a bit of a hurry to get the fry moved because (1) I'll never catch them all out of the parents' tank after swimup and (2) the parents ate the last batch of fry at 2 days old.
I'm trying to get 100% survival, not just a few, so I'm not going to leave them with the parents. Also, I want more eggs soon. Does anybody know if a little cloudiness in the water will be harmful to day-old fry?
