Hi, new here. I have a Nano tank with a pair of Harlequin and some corals for a few weeks now then i decided to add a Blood Red Shrimp with the consent of the Store owner in Cartimar saying Harleys + BRS are "OK".
Now the BRS was trying to roam around the tank when it got a few inches close to the pair the male started to attack him and got it's antenna but i wave them off.
So my question is.. are they compatible? :O
