I’ll go one better!
Thanks for the advice!
Angel update - all quiet on the western front. They are keeping their angelic names for the time being - but my heart is in my mouth!!
Thanks ... surprisingly well! They are ignoring everyone else. Doris the Bolivian Ram is lady of the bottom and they are respecting that and the only time I see any chasing is at the end of feeding time - just among the angels if they are all trying to eat in the same area. One seems to be the boss and the other two stay away. No fin nipping or owt like that and they just swim around!
