I added 4 platies 6 neon's and 1 kuhli loach to a new 45 gallon tank ( i put the old filter media in most of the water and all the gravel). The neon tetras are fine active and energetic so where the platys until about this evening when they where gathering around the filter ( internal fully) I have a current issue its pretty strong enough for them not to swim directly into it but im fixing that, know why they are doing that?
i added grave, water and filter media from ym 15 gallon which had the fish in it beofre i transfered them
