I recently posted about my angel fish/danios being sick and learnt that I haven't gone through the nitrogen cycle so that was probably why. My ammonia still hasn't gone up so my PH is at 6.6 and everything else is at 0ppm. So I have just been waiting for the cycle to get going. The other day I noticed one of my danios was bloated but I was told it is probably just a female and that they are bigger. Well today I fed my fish and watched them eat and I realized the bigger danio wasn't letting any of my other fish eat/was chasing them away. Also it is a LOT bigger then it was yesterday. I've seen it chase the other zebra danio before but I assumed it was just playing with it. But now I am thinking it is really sick. I posted a video I hope works.. I had to use photobucket because the uploaded on here was not working. help?!
