hungsta Posted April 28, 2005 Share Posted April 28, 2005 Hi Guys, I have had several batches of eggs my breeding tank and i have done a 50% water change because it was really dirty, this was when the bn hatch and have eggs yolks. I noticed that when the numbers decreased dramatically. Is this because of the water change? Will a large water change harm the babies even though the dad is looking after it?

xinguinsis Posted April 28, 2005 Share Posted April 28, 2005 Hi Hungsta, Don't think large water changes are a problem so long as you don't shift some parameters to much and of coarse nail them with chlorine.95 percent water change even on touchy stuff like Altolamprologus if the waters right is no problem But in saying that I've killed fry with 25 percent water changes when the water wasn't right so a 50 percent change could definitely do it.

hungsta Posted April 28, 2005 Author Share Posted April 28, 2005 Thanx for that... i will keep that in mind next time... BTW what is the best way to save and maximise fry count?? SHould i move the cave with dad in it to another tank? Also do older fry eat the newly hatched fry? Thanx Link to comment Share on other sites More sharing options...
Alan Posted April 28, 2005 Share Posted April 28, 2005 I am not saying it will never happen, but in all the years I have bred B/N there has never been a problem of predation. Mind you the breeding tanks have only B/N and proven harmless dithers. Alan Link to comment Share on other sites More sharing options...
xinguinsis Posted April 28, 2005 Share Posted April 28, 2005 I move my male intube with fry as I run trickle filters with grates that the fry can get through. I suggest waiting till a day or two before the fry will move out of tube, fill a small tank with water from the tank the males(minimise your changes in this instance) in and probably do it in the morning so he's less likely to take of at night time.If there in a sponge filtered tank I rotate the adults through tanks when baby count is high enough usually each spawn Link to comment Share on other sites More sharing options...
