Add the tank dimensions/filters, ect so the dimensions look like this : Length(150cm) , Depth(40cm), Height(60cm) (360.0L)
then I added a few fish and it went to this: Length(15cm) , Depth(4cm), Height(6cm) (360.0L) (<-stayed the same)
then I added more of a diffspecies of fish and it goes to this: Length(1.5cm) , Depth(0.39cm), Height(0.59cm) (0.0L)
and all that pops up, have tried closing it then reopening it, ect it stil doesnt fix it....
