stay awat from the auratus. the rest could be possible. yiour labs, peacocks are peaceful fish and may be picked on by the other fish. if you must have them, put them in first so that they will have settled in b4 the more aggressive fish choose territory. you can also help this by addint a ton of lage rock, more territory=less aggression. id forget the d.comp but if you must have it, put him in last and monitor it closely. as mike said, they can be bullies
another tip is to use sand if possible, moorii & lithobates prefere sand and it will make all your fish happier.
sorry i we popped your bubble
