I was guessing the ammonia coming from the comet's waste.
Alright that sounds good. I should get to it then.
I have to admit, I've only recently become concerned with the fish for once because now
I have to take care of them. The only instruction my uncle left me was to change half the water, keep the other half and scrub the algae and clean off the gravel. But my procedures have changed the more i get into taking care of them.
So, i don't use any conditioner so i probably have to go pick some of that up to. The only thing that i found that I have is
ICH medicine and fungus medicine.
Oh my, yes the comet and the two reg danios are OLD!! the comet is about a year old but the danios, they are probably 3 or 4 now.
