No they were not a pair. I am going to wait because the little guy eats lots still and swims normal for feeding time. Maybe just lazy and tired in the day from being picked on at night time
.Were the clowns a pair when you bought them? If not - one is going to get biullied - whether you acclimate them or not IMHO - I would just let them work it out - waiting in case there is a clear infection or damage
