Guppys starting to behave very odd

[smyth19]

I have three female guppys in my tank, and three of them are pregnate!! one has a very black stomach but is not that fat, the second is very fat but isnt that black(just a bit of black in its belly) and the third not that fair along. But anywayz to the point they have been actting strange today just flooting about the filter and i was wondering if they is there ready to have babies or just in need to chill out??
Any suggestions!! which would be must helpful

Thanx Alot joe!!!

The really fat one seems to be really pregnant. Even when they are pregnant they should still active though. You should check all your water parameters. If all of them are not active or hanging at the surface it could be ammonia poisoning or something else that is just as harmful.

I've just tested my water and it's at 0.0 for ammonia. + With the guppy that is really large it hasn't got the a really black stomach!!! its really confussing me. lol


Cheers guppymonkey for ur advice
