jaz1986 Posted June 7, 2004 Share Posted June 7, 2004 what were you feeding them? how old were they? what else was in the tank? when did you do the last water change? how stable is the temp? what is the temp of the tank? do you have any buffers in the tank?

Crazyfish Posted June 7, 2004 Share Posted June 7, 2004 I found that every time i did a water change when i had baby bn, they all died,except for 2 or 3 of the strongest ones, my mate gave me a tip that has been usefull, if your going to do a water change only take out 10% every 4-6 weeks with baby bn as they survive better in dirty water,he breeds thousands of these things and his advice did work for me. i hope this helps.

katanaone Posted June 8, 2004 Share Posted June 8, 2004 "as they survive better in dirty water"...crazyfish. i heard something like that aswell, was a long time ago but i think something along along the lines of adding a peice of driftwood to tank(as it slowly releases tannin) and feeding them zuchinni (i think thats how its spelt) at the moment i have around 30 baby bn in my grower tank with cobalt blues, rusty's and other malawi's they get a water change pretty often and so far none have died. hope this helps.

jaz1986 Posted June 8, 2004 Share Posted June 8, 2004 i don't see zucchini on that list novafishy If that is the case... then i am going that the water change did all the damage Link to comment Share on other sites More sharing options...
Rol&Jas Posted June 8, 2004 Share Posted June 8, 2004 I do 50% water change twice a week as the tank gets dirty. The bristlenose fry like that, I lost a large number when the tank was dirty last year. Also a few weeks before I had a big fry loss I moved some semi adults in there and they got into a breeding mood and attacked all the small fry.

Matthew Posted June 8, 2004 Share Posted June 8, 2004 G'day Trev This has happened to me as well. It is extremely frustrating with seemingly no explanation. A few things to remember. Copper will kill Bristlies. So always turn on your tap for a few minutes prior to any water changes. You can purchase metal sponges if you think this may have been the cause. Relatively expensive and fiddly though. Please use a decent product like prime to remove all of the nasties. On the weekend they often add extra chemicals to the water supply, so an extra amount (of prime or whatever) may be required? Please treat the water before you add it into the water. Aging in a barrel for a week is the way that I do it. I believe stability in the tank is the best plan. Either keep changing the water like Roland does twice a week, or leave it so that the fish get used to their conditions, then do minimal water changes. Hence the water remains relatively stable. (Either always fresh or just plain always the same). After they get above about 3-4 cm you are generally out of the woods, but believe me, this is not always the case. I once had a 6ftx17x16 foot tank with about 150 x 5-8 cm bristles all die on me, after a water change. The only reasons I can think of are the water was high in chemicals (I wasn't aging it in barrels at that stage) or the tank was overcrowded and some disease that was not visible struck. All but 8 died within a week. They seemed to be starving for oxygen, climbing the walls of the tank and then they would just die and float to the bottom. The cichlids that were in there with them were fine. PS. There was heaps of filtration, air and the water change was less than 5%! PS. If you ever work out the problem PLEASE post it up as it happens to lots of people. Link to comment Share on other sites More sharing options...
Crazyfish Posted June 9, 2004 Share Posted June 9, 2004 Also sorry to say this but you could have bad parents with a low fertility rate, which produce babies that cant handle disease,or cant handle change with water chemistry, although i have been also trying a new way of raising the fry and it seems to work while im doing it, as soon as i see the bn eggs i cover the tank with a towel so no light gets through, i raised all the fry to about 3cm in 6 weeks, took the towel of the tank and the next day they were all dead, maybe the light is also a factor!
