...with my aquarium. I have had 6 zebra danios and 3 marble mollies in it for about 8 weeks, all was going well... until recently. They started hanging at the top of the tank all the time, and then slowly, some of the danios were swimming on their sides and upside down etc. - I belive this was a bladder infection. I lost 3 of the danios. I gave the tank a good clean last week, and a 40% water change - and I have since lost ALL of my fish...!
The mollies and 2 of the danios seemed to be dead - but at the BOTTOM of the tank - when I went to get them out, they were actually still alive, but only just. Why were they sinking, not floating??
I have a small amount of brown algae on the rocks/glass - so I was thinking of getting an Oto to get that sorted, but I am worried that the water my be 'polluted' from all the sick fish...
My question is, now I have an empty tank again, shall I do a partial water change before I add any more fish, or should I start over and clean/change it all??
