I’ve had a couple air of snowflake clownfish for 2 weeks I went and bought a new purple stripe dottyback yesterday, the dottyback was out right away and seemed comfortable even ate this morning but the small clownfish keeps chasing it around, it doesnt bite it just chases it. I put the clown in an acclimation box but I was wondering how long I should leave him in there? I have a spare heater that I put inside but I have no filter would that be fine?
