Hi
Just wanted some advice, i've had my 60 ltr tank for over a year now I have 5 rummy nose tetras and 2 neons,(which have been in the tank since it was cycled)
MY son's friend works at the local aquarium and he tests my water quality weekly for me and he always says its pertfect, i do weekly 25% water change, my problem is every time I introduce new fish to the tank within 4 weeks the new fish are dead they seem perfectly fine then after a few weeks they just seem to die really quickly and my original fish are perfectly healthy, sons friend has advised me but just wanted some more ideas as to what is going on,
