I have (5) full grown Glolight Danios in my 20 gallon (24" long) that I bought less than two weeks ago, and 1 white cloud and 6 amano shrimp 2 olive nerita snails for tankmates.

They used to always school (very active fish!), one has now stopped schooling for the most part and swims mainly in and around my clay pot or around the outside. It doesn't appear ill because it's still active and looks well and eats well, it just doesn't swim very far and it chases the other danios when they come close to it.

I also just did a 25% water change yesterday where I did a thorough gravel vac (which I always do), the temp is 76 and the pH 7.2 and the ammonia 0.

Is there any other reason that the fish would be hovering around this pot other than breeding? Is there any other way I could tell if she was breeding? I think it's a her because she's more grey and less colorful, and 3 of mine are very colorful and 2 are more grey. (So since the two smaller ones are more grey, I don't think the one is sick.)

I've been looking online about their breeding habits and I don't see anything here about them becoming territorial over a certain area, etc.


Months ago I lostthe original batch of white cloud minnows mysteriously, and about 3 weeks later after a thorough plant cleaning - I discovered a tiny fry who was this big | | !!

It took 1.5 months but it succeeded in becoming a full grown Golden White cloud, so I guess there has been breeding in that tank before?

Thanks for any thoughts.

do you mean "Glofish"(tm)?

danios are egg-scatterers, and do not pay any particular attention to their eggs and fry (other than eating them if they see them, apparently).
 
my mistake. didn't know there were glolight danios.

but the link does agree with me that they're egg scatterers :)
 
I have had 1 or 2 that do not quite stay with the group. As to the one spot hovering I can only think that it is the spot that that particular individual feels safe. It may be just mine but with mine they seem to more skidish than other danios, and stay close to cover.
 
Thanks for everyone's replies - it could be a security thing I guess since it's just shy of a full school (though I bought the last 5 they had, I'm hoping a few more will come in.)

And she does appear to be coming out more once in a while, although I notice she still hangs around the bottom of the tank by the gravel and swims down there, when alot of the others are all over the place.
