royal gramma compadibility

[invertaman]

hey guys,
i have a 20 gallon with a tommato clown, and a 3-striped damsel. and inverts. i was wondering if i could add a royal gramma. i have never kept one and i dont know if they're compadible. i know 3 fish is pushing it but ive kepped 3 fish in 20 gallon before and they were fine.

the damsel might me aggressive towards the gramma....i introduced a gramma a few weeks ago to my 110...the damsel was a wee bit aggressive towards it for the first day or two..but once your gramma finds a good spot for it to hide, he will most likely be fine...but make sure he gets lots of live rock to hide in...

I think you'll be fine. Grammas can really hold their own.
