3rd Guppy Died Today :-(

[LuluZuzu]

Hi all,

I have a 125l tank, it has 9 gupys in, the tank was cycled, which took around 5 weeks in total, and has fluval filter and some real plants.

I bought 2x Spot Lemon Cobra guppies. This was about ten days ago that I added them to the tank along with the other guppies.

The 2x lemon spots after a couple of days always stayed in the top left corner, just sought of swimming near the surface. They had a couple of days swimming around with the other guppies then seemed to stay in this spot. On Thursday, one of the lemon spots was dead at the bottom

The other lemon spot was still floating at the top, just swimming as he did before.

Then yesterday, Sunday, this other spot was dead

I thought it might be just the batch that they were in. I noticed one of the other orange coloured guppies was doing the same swimming thing at the top. I actually didn't pay much attention, thinking maybe it was just bad batch. This morning, the orange guppie is dead

They seem to have slightly bloated tummies. The water is showing as fine, so not sure what it can be ??

Any ideas?

Thanks

What are your water stats.
What do you feed your fish.
Are the scales sticking out.
What does it look like when the fish go to the toilet.
Any fish laboured or heavy breathing.
