Most likely yes. To be sure reduce surface agitation, by raising your water level, adjusting the flow of your filter, turning down bubblers/airstones, etc. Place a few floating plants, live or artificial in the "stillest" corner. This will enable a good place for a nest. Sometimes with harder water or water with alot of protiens you can get a very identical looking bubble grouping that looks like a nest. I get them in some plant only containers that have no fish. My betta takes up a corner where I planted Nymphaea (lilies). The green leaved ones dont require much light, red ones need high light. They shoot "lilypads" to the surface and the betta has claimed that. When they do blow nests you can watch them do it, or add to an existing one. Pretty interesting.

I recently added a fake floating philodendron with lots of hiding spaces and big leaves - I'll watch for nests being built in it. Other than that, it might just be from the bubbler like you said. I'm not too optimistic that I could actually raise fry in this tank anyway, it's a pretty busy community tank. I was more just wondering if this is what I'm seeing. Thanks.

Are the gourami's and bettas (M&F) all in the same tank? If either the gourami's or betta spawn remove the fry with the father to a seperate aquarium. The males will injure or kill any fish that comes near the nest. The females and other fish see the eggs/fry as a snack.

Ummm.....if you want to breed betta and or your gouramis....they should be moved to another tank by themselves...The males build a bubble nest and then the female is introduced......then you can observe the breeding actions ...the male will wrap himself around the female....under the bubble nest....if you look closely you will see the eggs float up to the top where the bubble nest is. The female should be removed as soon as they finish spawning...The male can be left to tend the nest and eggs until the fry go freeswimming.....then he can be removed from the spawning tank too....when the eggs hatch...you will see little sticks hanging down from the bubble nest....occassionally they will float down and back up.....this will go on for about 10 days ...then the fry will go free swimming....fry can be fed micro food, micro worms and then newly hatched brine shrimp, then onto regular foods.....Chances are you will not be sucessful in a community tank....

The bubbles may be from the betta or gourami......but more likely to be from your filters. There is too much going on in your tank, to have bubble nests.

Thanks I don't want to breed them, just wondered what the bubbles would look like for a nest. I agree that no sane fish would try to reproduce in my tank. And yes they are all in the same tank.

I kept a betta (male) and about 4 dwarf gouramis together in a tank way back when. With in 2 weeks the betta killed the gouramis. On another ocassion I had almost the same mix, no problems. I know its not reccomended to keep gouramis and male bettas together. They are close relatives and have alot of the same traits. Didn't know about that then, wouldn't try it now. That was why I asked. I kinda meantif they did spawn, remove the male and eggs or the other fish.

How do you Keep betas with other fish? Ive allways wanted to have a Betta with other fish, but ive allways been told you cant cause they like solitary and are very agressive. And if so what kind And have you seen those terium/aquariums where the aquariums on the outside and the teriums snugly fit on the inside? would that have any bad affects on the fish?

Cheers

I have kept bettas with, angels, neons and small tetras, oto ctas (almost any cat/pleco), Gouramis (not reccomended), guppy's ( also could be trouble), a school of small tiger barbs ( Definatly not, but I was a kid and didn't know) Clown loaches, platy's, and some combos I cant even think of now. As with any fish, especially a potentially agressive type, have plenty of cover, plants rocks, caves etc. and observe closely for a while for agression. A few "sparing" episods are common, as long as no damage is done.

I have a betta in my goldfish tank and he loves it in there. I think he thinks he is a goldfish. I have no problems with him and the other fish and I use to have a big tropical tank with a betta in it and never had any trouble. Hmmm I might just have to go get me a female betta and see what happens with my betta in a bowl.Looks like he's lonely and needs a girlfriend...

bettas and goldfish....take completely different conditions.....so this is not good fish keeping practices.
Goldfish like colder water temps.....while bettas like much warmer temps.....

Read up on breeding bettas before getting the betta a "squeeze"- NJDJS. If they spawn it could be deadly for the female.

Betta do fine with other fish as long as those other fish are not agressive or fin nippers......but housing a betta and any goldfish is not a good combination........
