Adding fish

[The Iceman]

Is it possible to add a royal gramma after a 6 line wrasse after a week of having the wrasse? I know the wrasse should be last but it was on sale and the gramma cost more. The wrasse is a juvenile still

Even if you added both those fish at the same time they would fight

Tank size and amount of LR? I have both of these fish in a 29 with no issues so it is possible. Gramma should be last as they can be territorial. Six lines are very peaceful fish IME. Just need a good amount of live rock for them to graze on.

It's a 20g long with about 30lbs of live rock. Also have a ocellaris clown but he was put in before the wrasse
