There's 5 females and 2 males now. (males only go in to mate) We have guppies mollies plattys, gold barbs, a plec, kahuli loaches, 2 glass bloodfins and some neons. Water is spot on with api master test kit.
Have done a 50% w/c and added aquarium salt. All the others look really healthy and happy, just these bloomin guppies!
Oh tank is 125 litre. Previously had high ammonia and nitrates but that's been sorted around 2 weeks.
