This evening I decided to start getting things ready for spawning. I still have a few questions; so I'll be using this thread to not only note my progress, but also for asking questions etc, so please keep returning

.
Anyway, for spawn attempt number one I will be using the following two fish:
Ruby; Orange Female Crown Tail from spidermanbettas in Thailand.
Gabriel; Pink/White (please tell me what colour he is, lol) Male Veil Tail from a LFS. (Picture taken by my brothers friend Lisa)
I have started setting up the tank, and this is what it looks like currently:
I have a sponge filter on the left hand side, which is currently running, a piece of bubblewrap for Gabriel to use for his bubble nest, and a silk plant.
I will be adding a 50watt heater by Monday, along with a floating live plant and a styrofome cup so Gabriel has a few choices for his bubble nest.
I will most likely be using a two litre Coca-Cola with the bottom, and top cut off for Ruby to be in until I am ready to release her.
I will be using the light that sits on Gabriel & Chucks tank as the light for spawning, and replace theirs with a desk lamp.
This leads me to my first question. Do I leave the light on 24/7 when attempting to spawn, and when the fry have been laid, and are first free swimming, or do I just continue with my usual 8 hour a day light scheme.
I have also read conflicting information about the filters (not to turn it on until after the fry are free swimming, and have it on all the time). What do you guys do?
Next Wednesday (pay day) I am going to pick up some live brine shrimp for Gabriel and Ruby, and also see what I can find for fry food, I think a LFS has brine shrimp hatcheries, so I might look into that.
