Glad to hear your ray is pulling through . I would have done exactly what you did and not moved the ray that was stressed .
I have 2 females and a male now and am dreading the day the biting starts
she started eating pellets yesterday and is doing great with no interest from the male
she is still a bit shy and covers her self in sand for a few hours each day when the lights come on but apart from that she is now doing great
i now feel confident to post a picture of how bad she was beat up all this damage happened over night which is one of the bad parts of not having your tank in the house were you can keep a close eye on things
i still feel if i had moved her she would have been history
i will post a picture later of how she is now just 1 week after this picture and a 7 day treatment of melafix
