Hey everyone, looking for some advice on a clownfish pairing situation that isn’t improving.
I have a 30g reef and originally had two ocellaris clowns (had them for 4 months) , one larger and one smaller. The larger clown stopped eating, became lethargic, and after about two weeks I made the call to return/rehome it to my LFS because it was clearly declining.
To keep my remaining clown from being alone, I picked up a smaller ocellaris as a replacement. The goal was to keep the size difference clear so pairing would be smoother and to avoid two similarly sized fish fighting.
Unfortunately, after introduction, the larger remaining clown became extremely aggressive:
• Constant chasing
• Biting/nipping
• Pinning the smaller clown in corners
• Shaking aggressively nonstop
The smaller clown eats when food is present but spends most of the day hiding or being chased. I tried:
• Lights out early
• Isolation box (bully in box for ~6 days)
• Reintroduction with lights off
• Water change before release
As soon as the bully was released, aggression immediately resumed. The smaller clown does not shake back or show submission; it just flees.
At this point, I’m leaning toward removing the aggressive clown permanently and replacing it, but I want to do this the right way.
My questions:
1. Would replacing the bully with a larger ocellaris (same species) be the best move?
2. Has anyone had success resetting pairs this way when one fish becomes overly dominant?
3. Is there a point where a clown just becomes unpairable?
I don’t want to run a solo clown, but I also don’t want to keep stressing or injuring the smaller fish.
