Best light cycle for fry?

Do you prefer any particular light cycle for new fry? Or is it 24h better?
If relevant, these are German blue ram fry that became free swimmers today, and the female is in the same tank.

 

Fry don't care about light. Adults don't either. Ambient light for them is fine.
And if by 24h.....you mean light 24 hours a day, it will stress them, and grow a ton of algae too.

 

There is loads of algae in the tank already, on purpose. It is a breeding tank, not a show tank, so I don't mind about the way it looks really.
I read a post over here (I think it was Butterfly) stating that with continous light the fry's (Angels in that case) survival ratio was higher due to more feeding sessions. However, I agree with the fact that it will make the mother neurotic.

 

That's interesting. IME, they will eat with or without a light directly over the tank. I have a couple tanks that have light colored backgrounds, with white gravel. I never turn the lights on in these tanks because the algae will grow quickly in them. The fish eat whenever I feed them. Anytime of day or night. I put food in the tank, and they eat it.

Or do you mean the fry are eating the algae?

 

The idea is that the tiny GBR fry will feed on the microfauna & microflora related to the plants and the algae; at least in theory. They are too small for Baby brine shrimp. They were actively picking on the algae so I guess there was a good amount of infusoria in the "dirty tank". I fed them banana worms as well and their micro-bellies swollen up . The thing is that the B worms can live 24 hours in freshwater so with a longer light period they will be less likely to starve during this hyper-metabolic life stage . From what I read GBRs fry do not seem to feed at night. Anyway, I am not too fond of keeping the lights all the time.

 

Once the room lights are off my fish will not eat. If u turn the light back in it take 5-10 min for them to want to eat.
