First Tank :)

I've re-arranged the plants and its looking better

Need some advice... My angelfish unfortunately passed yesterday but i have no idea why? My levels are perfect, tank is clean as it can be. All the other fish are fine and he was fine too, just suddenly died :/ no signs or diseases or anything...
Any idea what this could've been?

Maybe by moving plants around u open a gas pocket in the substrate. If u don't vacuum the gasses can and will build causing a toxic gas to leach in the water possibly killing the fish. If all your water perimeters are good and stable you should not loose fish in quantity like that. I can see if one fish died! It could be considered natural causes. But if a bunch meaning more then one, dies then something is more then likely the cause of death.
