HI! Not new but looking to add

HI All

I have a FOLR

30 Gallon Tall (sigh)

40 pds live rock

Remora Aqua Sea Protein Skimmer

Penguin HO 200 filter

3'" Live sand



1 Valentini Saddle Back Puffer

1 False Perc Clown fish

1 snail (Puffer likes to knock them off wall so its an exercise in futility to buy any more)



Clown is a bit territorial since I've had him the longest at almost 6 yrs. And he's been alone since i lost my Huge 5" Velvet Neon Damsel 1.5 yrs ago

He pushes the Puffer around a bit. Puffers been here for 7 months.



Looking to add another schoolyard friend into the mix just not sure how aggressive to go.



Would hate to see anyone ganged up on.
