New tank - new owner help !
#1
I’ve recently bought 2 mollies and 2 guppies ( these are my first fish) and had set up the tank following all the instructions careful , I have the water set at 26 degrees Celsius and left the tank with the filter on for 48hrs .
Fast forward to having the fish in the tank for 48hrs and I woke up to find one of my guppies dead at the bottom of the tank ( I’ve removed him and have him set on the time in a small bowl with tank water ) and now my two Mollies are acting strange and staying to the bottom of the tank ( still moving their fins but not swimming properly )
Iam really worried that I have done Somthing wrong regarding the tank but have no idea what and really don’t wanna cause anymore fish to die ! and everything online says it’s either too hot or cold in the tank but the thermostat says it’s the perfect temperature?
