Yesterday I added 6 cardinal tetras to a cycled 80L tank containing 1 adult Guppy and about 20 Guppy fry (the biggest of which are the size of the cardinals)
Overnight one of the Cardinals died and I found it behind the filter. Today one of the Cadinals seems to be almost entirely missing its tail and another seems to have white raggedy edges on one fin and a tail.
I am frequently testing the water and it is consitently 0 Ammonia and Nitrites and 40ppm Nitrate (this is the levels in my tap water also). The ph is 7.4 and the water is hard. I realise that this is not ideal for the cardinals but apparently these have lived in the same tap water in the lfs so I was assured they would have no problems.
Despite the zero ammonia and nitrite readings I have done a 50% water change as a precaution. I don't think the Guppies are harming the Cardinals so I am wondering about a couple of things:
1. Could this be finrot? If so, can fin rot cause one fish to die and one to nearly lose it's tail in 24 hours?
2. The filter is a bit of a monster - It is a Jewel filter and is as tall as the tank. The guppies sometimes get stuck inside it if you can imagine such a thing. As I found the dead tetra behind the filter, could it have got stuck there? Could the filter have damaged the other tetra? The guppies don't seem to show any ill effects.
Any advice would be greatfuly received!
