No. I didn't do anything. I mean, their tank was always mostly about them to be honest with you. Just because I love them. I let the plants go mental, which may look a little untidy but it's what they like. I did have some baby synos in there but as the biggest male grew up and became 'active' he started trying to take chunks out of them so they got moved out. All but one. They don't mind the bristlenose girl so she'll be getting a partner soon.

It's a 35g long they live in with some self bult slate caves, one piece of bogwood and tonnes of live plants. Because of the vast quantity of plants I also have two filter running. One at either end. The water simply does not flow the length of the tank so this stops any dead water patches happening, hopefully!
The gouramies I got to start with I was told were a ratio of 1 male to 3 female. Turned out not to be the case. Had two males. The big obvious male and a far more laid back male with less developed finnage. Sadly one of the females developed a kink in her spine (pos tb but since she's still alive and well elsewhere in the house still not sure) she had to come out, leaving one female.

She's the mother of the fry. And she's a big egg producer. She recently spawned again with the big male and I had to take her out a few days ago to give her some rest. Poor thing looks exhausted. I recently introduced two younger girls to the tank but I am almost certain one of them is male too. *doh* So he will have to be changed for a female. Pity since his coloured up utterly beautiful. He's blue with a yellow tinger on his lower finnage. I shall be sorry to part with him. But he does seem to be a fry eater so it's probably for the best.
Am sure I've said elsewhere in the thread about what I feed them. They have flake food most days along with live food (bloodworm, brineshrimp or daphnia, although less daphnia then the others) The also get frozen food including the above and krill. I also use cat fish pellets and plec food in the tank so there is a great deal for them to pick from. And the very small amount of algea that grows too. Now they get baby food in there too!

Still got so many I need to move to the fry tank it's mad. But the laid back male tends to them like they're all his own and protects them from harm. He really is the sweetest thing ever.
If you want to breed then like with many egg layers, give them what they want. Gouramies needs are easy. They love space of their own and lots of plants. Like an underwater jungle. I never treated them differently when they spawned, or are spawning. I never stop feeding them. If anything I make sure they all have some each so no one's missing out. With the exception of the new 'male' none of them eat the fry, ever. I haven't changed the temp, ph, lighting, feeding habits. Nothing. I think they just feel happy enough and secure enough to treat it as their home. It's not in a particularly quiet place (The tank) being next to the living room tv and my computer is opposite them. So I can turn around and watch them anytime. They don't mind the noise, they recognise me as feeder and mad person who does odd things sometimes. And I believe there is a level of respect involved. They know I'm not there to hurt them, even when I do water changes or spend forever picking out snails. Does take some time and patience to get that with any fish, as I'm sure you know.
I'm no expert. There are many people on this site who know alot more then I do. I've just been fortunate enough to have gotten it right and the gouramies must trust me enough.
I wish the best of luck of course and wanna see pics!

If you get really lucky they may even spawn in the afternoons like mine usually do. I have front seat viewing for that and it's wonderful to see.
Hugs,
