How can I encourage my betta and Gouramis to build bubble nests is there certain things that need to be in the tank so that they can build bubble nests.
i dont' know about gouramis, but i notice my bettas will build extra extra large nests when i give them more food than usual! and better food too such as frozen bloodworms and things.
Attention also helps too my bf's betta was moved to teh dresser where he coudlnt' be seen as much as he refused to blow a singel bubble, when my bf moved him back to his desk with him, he build a huge nest
i didn't know gouramis built nests but as for ur betta, they just build nests wen they are happy, feed him good food and give him space, he'll build ya a big one
In my experience bettas always seem to be more determined to make a bubblenest when there are other bettas/betta like fish around. I have a female in a small half a gal tank right next to my 10 gal which houses my male betta and several other fish. He spends a lot of time flaring for her and building his nest to get ready for the spawning.
Mine is temperamental. He had a huge one until I went away for the weekend and when I came home it was gone. I think he was sulking because the "fish sitter" doesn't spoil him like I do.
