Been reading online and have a large Clarkii and fairly large percula/ocellaris and 4 anem. Clarkii is hosting long tent. anem., would like another clown to host others. Have just put in a small percula/ocellaris and he was getting beat up so bad I put him in a "breeder box" in the aquarium. It's 90 gal. Am I going at this the wrong way, adding smaller to larger, would like another Clarkii but now not sure whether to go smaller or not. I turned the small one out and they are chasing but not as bad as this am. Clarkii also seems to be after other large perc/ocell. Should I take this little one back to the store??????????????????
