I have two zebra danios (1 1/2") in a 10 gal tank. I also have a pictus/pleco & upside down cat. I know it's way too many fish (the pictus/pleco & upside down are just under two inches each) but I have a 100gal cycling for them, it's just not ready for them yet.
I purchased the danios with the intent that they would be the cycling fish. I've had them for approx. two weeks. I noticed that one of them was beginning to look like it was about to explode. I went and read up on them and looked at images of Danios that were full of eggs.
I'm convinced that mine was.
Just two days ago her belly was back to normal and at the same time they have started chasing each other around like crazy. They take turns being the aggressor. It's non-stop. The only relief they give each other is at night once the tank lights go off.
What's going on with these two??
I'm not sure that just two will be enough to cycle a 100 gal.
How many should I have total?
Since there's only two (and not 3 or more) is this why they are going off on each other??
Thanks in advance for your help! Kym
