Once per day for 10 days? Yes. He is the only fish in the tank. He also share his tank with 3 adult and 2 baby malaysian trumpet snails SirLooks like splits to me, there aren't any other fish in the tank? Anyway the Artemiss should help with that too. Yes you have to add it every day, for a minimum of 10 days.
I will certainly continue even after 10 day. 1-2 days after 10 day period? Once per day? The bottle says every 12 hours to dose and it confuse me.Well he obviously survived, but apart from the usual shipping stress, may have suffered from ammonia and nitrite as well as the temperature, it comprimised his immune system and as a result he is now having health problems. It takes time to heal, and you can continue with the Artemis even after the 10 day period.
