Yesterday, I spoke about a danio of mine who was acting a bit weird. He stayed away from his fellow danios and stayed near the top of the water and had trouble swimming, now I can't find him ANYWHERE!

Now I have a BIG FAT zebra danio. He is so fat that he can hardly keep himself up (although he tries very hard). By the way my water chemistry is 7.2 pH 0 ammonia 0 nitrate 0 nitrite

My questions are:
1. Could he have eaten the missing danio and that is why he is fat?
2. Is he ACTUALLY a she and filled with eggs?
3. Is there some kind of disease that makes fish so bloated and can't swim right?
4. Are some danios just fat like this?

Well, I changed the 25% of the water, and he is dead. I also found the missing fish, he is dead too.

Very sad

Sorry about your danios.

Thank you. So now I am down to five. Four are very healthy looking and school together, while one is smaller and isn't part of the school (maybe they don't allow him to school with them because he is small?). The little one just stays away, I hope he's not sick.
