Yes, that is the exact article that I re-read today.
In fact, the only reason I made my choice to try this method was because I was too lazy to take the male out 3 days ago. Then I thought that I would like to try this method anyway since I have been wanting to do so for so long.
About your male not eating, I think this has to do with age because one time I left my male in the tank with the fry for 4-5 days because I forgot to take him out and he didn't eat either...he was 9-10 months old then later down the spawns, I had a 4.5 month old male that ate a lot when he was in the tank. They say not to feed them while in the tank, but I do anyway. I don't feed my males while they are spawning or are chasing the female, only when they are usually working on the bubble nest and flaring at the female in the glass.
As for my male currently......He eats like a beast. Wow that is definitely the name used as "cool" out here, but I was meaning more of the monster kind of beast.
I just fed him and he ate 6 pellets, and 3-5 freeze dried bloodworms. WITH NO BLOATING WHATSOEVER
