I'm so sorry to here of your recent loss.
I must admit i was worried about mine when i got them as they were breathing at a much higher rate than my other fish.
However i moved the spray bar for my tank so that i was getting maximum water agitation and all seemed to settle down after a day or tow.
Ahh stunning fish the Ram. They took a about a week to settle in. In all fairness are still growing in confidence, with their other tank mates. Their colours came back after a day or two and are now back to their stunning beauty.
Mine too split up and remained that way for around a week and a bit. Although now they seem to tolerate each other and even swim together for very short periods. Before the male gets tired of the female and chases her around for a bit.
Lovely fish and i'm so glad i got them.
