Hi all,
May I know how do you guys raise your bn fry??
1) Food?
2) water change?
3) tank size
etc.
Below is what I am having/doing now.
1) I feed mine zuchinni, algae wafer, flake and now trying coz lettuce as been told they love it.
2) only like 5% water change weekly but was told by a guy last night that he never do a water change to his bn till they are like 3-4cm.
3) I am having 2 2x2ft and 1 3ft on a small sump, they breed in the 2ft and I have moved them to the 3ft after i see the fry abt to come out of the log. so the water are all same.
the problem is I never see them eating, they are "sucking" on the side glass and after few weeks, they will start disappear... or dead body ard the bottom on tank Unhappy
Many thanks in advance, had lost 2 batch of common bn. Unhappy
Please help

I like keeping my bristlenose fry in confined quarters so that they do not have to search for food too much. Incidentally this is a rule I apply to all my fry.
With confined quarters and increased amount of food per water volume, makes water quality a very important issue. If you change too much of the water all at once unless all the parameters are identical; and it never is, the fry gets stressed. And if you change too little, the fry will get stressed anyway!!!
On the up side the common bristlenose fry are tougher than many other catfish fry in my experience; i.e. Corydoras fry. But they are not bullet proof.
So after all that verbal garbage :roll: what I prefer to do, is to put the fry into a fish-net-breeder and hang it in a tank. This way the fry are confined to a small area but have a much larger water volume for waste to disperse. I feed the fry all sorts of pellets and veg. As the pellets crumble etc. the fish in the tank polish of the remaining food through the net. In a standard fish net breeder you can (or I do) get a batch of fry to a size that you commonly see for sale at LFS.
Warning: Fry that still have their yolk sacs can be sucked through the net by large fish, including adult bristlenoses; that is if you hatch the eggs in the net in the first place.

Yep - that warning is a MUST. Unless you have a thin layer of gravel at the bottom of the net, otherwise wigglers with the sac will be in danger of adult fish outside.
And Bristlenose has the ability to "climb" into the net during the dark (they'll reach all part of the tank in the dark), so either you leave the water level low enough to stop them or get a cover made for the net.
Having a small powerhead blowing from one side of the net keeps water well circulated through the net.
