Addendum 1 : Another tipIf the pair need more tempting then let the tank receive a small amount of morning light....or mimic that by having a light shining from sideways onto the top of the tank for a few hours.
Addendum 2: When do Gouramies reach sexual maturity ?
Gouramies will often breed at about half size; the smaller species need to be bigger than that though.
But, a half-sized adult may be a stunted 'full-grown' adult one as well.
If the male is starting to show signs of breeding (eg colours and behaviour) then they are ready for breeding.
Pearl (or Lace if you wish to call them that) grow to around 4 to 5 (or 6) inch body length (excluding tail...so add an extra inch to that for the tail). You tend not to find too many at that size.
So they will breed at about half that length if they have come to sexual maturity.
I think that many people simply walk by pearl gouramis in the shop as they are small and look drab (the gouramis, not the people ). That is a great pity as they are one of the fish that built the hobby.
What does a gourami cost? 3 to 5 euro (maybe a bit more for some)...that is nothing for a great fish (if you watch out for some pretty duff virus laden ones though).
Maybe the Chocolate gourami breeding article is next, but I wanted to do a piece for people starting out in fish keeping to have a go at breeding fish that need a little work (as opposed to kribensis or guppies) but are pretty easy to keep. Chocolate gourami are not easy to keep, not easy to breed, and not something I'd be tempting someone starting out to try.
