Help Stocking 50g

Royal gramma can be aggresive with anything that looks like em. it wont be easy adding another member of the damsel family with the pair of maroons. I would add a small tang. Remember blue,powder blue/browns are fragile. check you temp first thing in the morning, before lights turn on and after they turn off to see how much the temp change thruout the day, drastic changes will stress those fish and get em sick. If you have any problem when adding new fish you can try this trick. get a small mirror and place it outside the tank so the fish acting aggresive can see its reflection, it will think its another fish in the tank and will attack the reflection and not the new fish. leave the mirror for 2-3 days till he calms down, also addin the new fish with the lights off helps a little. good luck

 

DON'T ADD A TANG! A tang in a tank that size will only stress it out, which could cause ich, which causes fish to die. I would try a Dottyback or a Royal Gramma.
