1~What type of fish is afflicted? I found one of my coral plattys on the bottom of the tank this afternoon, it was 1/2 eaten! It had faded to near gravel colour Yuk
Then that evening a female guppy suddenly floated dead. I think it was pregnant & it had a bruise in one side and a dark red blotch on the otherImageUploadedByAquarium Advice1392675415.995511.jpg. The rest seem fine and started whisking about the tank when I approached the tank to remove the deceased. They thought they were going to get fed



2~What are your tank parameters 0-0-5 ph 7.4 25.6 C


3~ How large is the tank? 70L 3 months old


4~What type of filtration are you using? Juwel super. I think it's 400L per hour


5~How many fish are in the tank? See signature please


6~When is the last time you did a water change and vacuum the gravel? I do a 30% pwc every week. Last change 2 days ago


7~How long have you had the fish? The platty I have had about 2 months. The female guppy I got about 3 weeks ago. It was 1 of 2 I got to stop males fighting


8~Have you added anything new to the tank--decor, new dechlorinator, new substrate, etc.? No. Nothing


9~What kind of food have you been feeding your fish, have you changed their diet recently? Flakes and pellets. I haven't changed their feed.
I usually feed 2 flakes and 5 pellets alternate days. Yesterday however I tried the "as much as fish will eat in a minute" so I fed a lot more
 
Sorry. Don't think signature posted properly

This is what I have now - after the deaths

10x neon tetra
5x five banded barb
1x sunset coral dwarf platty
2x golden oto
2x guppy
1x betta splendens

61x30x43cm 70L Juwel
 
Update- there's been no further deaths overnight

Anyone any idea what caused these 2 deaths?

Thanks
