that's good to hear that boys don't all make huge bubble nests......
i know peaceful (my profile pic) use to make very small little nests but they weren't very frothy like on some pics i have seen here.
now with his new home being the baby biOrb, the filter makes bubbles at the top of the tank that i am not sure if he will ever try and make a bubble nest in that aquarium because a bubble nest would never stay put even if he tried.
