I have a friend that hatches BBS so it must be fairly easy (I have not tried it), so maybe give it a go for the start to give the baby fish the best start then move on to other food? I guess there is no difference than frozen brine shrimp though!
I have never had baby fish, but feed all my fish baby fish food anyway as they are small fish. I think it is the same as normal fish food just powder! I dip a pln into the tank to wet it, then into the powder food quickly, then swirl the pin in the tank to feed the fish!
Ooh BBS is that 100% necessary? If I can get through without it I'd like to. Feeding frozen BBS, frozen cyclops, algae wafers (they crumble fantastically under water) and hikari first bites at the moment. They're also probably eating loads of micro life and stuff in the mulm. I can probably hatch baby brine for a little bit though.
Also jayc what do you think, seperate or let the parents raise?
