I have a 70litre tank working about 3 weeks now is it safe to add any snails?
4 danios (2x gol & 2x zebra)
If the fish are doing well, there is no reason you can't add snails. How are your water parameters, have you checked them with a test kit? You want to start off slow to give the tank time to cycle. What type/size of snail and how many?
I dont know what they are. Someone off freecycle is giving them away as have too many. She says they are about 5mm in size I have a 70l and 15l both have been going for 2-4 weeks and parameters are both great
