Got the tank a week ago, it's not cycled.. but it doesn't matter as you don't want a filter going with the babies.. you will want to turn it off during the breeding.. make sure to remove it and clean it out, as if you let it sit then any bacteria that had grown on it will die while the eggs are in the nest and when you turn it back on, could push out lots of dead bacteria..
Keep in mind not to breed in the male's home tank.. he should have another tank to condition in and be introduced into the breeding tank when it's time to breed, and then at some point after the fry have hatched you will remove him back into his home tank.
How high do you have the water level? May want to up the temp just a tiny bit.. 80 is fine, but sometimes the cooler the water the longer it takes to hatch the eggs.
What is a standard fin betta?
