clownfish aggression

Hello Everyone! New to this. Need some help. I have had my ocellaris clownfish for 4 months. All gone well, cycled tank - also have 4 hermit crabs. All of a sudden one of my clowns starts hiding in bottom corner of tank swimming up then moved to top corner at surface behind filter output...

I have a fluval 13.5 gal that I’ve had for like 5 years and a clownfish in it for the last 3. He normally would swim at the top in the corner of the tank but recently has been sitting at the bottom near a rock that my pistol shrimp and goby have a tunnel under. And about a week ago I noticed...

Is this normal dominance behavior? I have linked to a video (trimmed from 3 min to 1): These two clownfish have been fine but recently the clearly bigger one is relentlessly bullying the smaller one. The assumed female is causing trauma to the assumed male (frayed fins, white mouth). Yet the...

Hi all, I recently started my tank 1 month ago, and once cycled I added two juvenile, captive bred ocellaris clownfish from my LFS (one black and white one, one gladiator). The black and white one was slightly bigger, and was instantly more aggressive/dominant towards the gladiator. I know that...

Hello, I have a question about whether I should add all the fish at once or one by one. My new tank will soon be ready for new fish. It is a 20-gallon tank. I plan to have a pair of clownfish, a valentini puffer, a falco hawkfish, and a diamond goby. My friend advised that I should add the fish...

I feel like the answer is probably a hard no, but I’m throwing out the question anyway. If I have a fully mature longfin domino ocellaris, and I add a baby-baby bicinctus, is there a potential for pair up? Or is it more likely that one will still inevitably kill the other? For context, right...

So my female clown (I'm assuming is female cause her size) I've had for 3½ years while the smaller one (assuming male) I've had for maybe 2 years. They've been doing this, and mouthing up sand, and tailing finning (kicking) sand up also. (I know my algae is bad) But is this submission or mating?

Hi! I've had a pair of frostbite clowns for a few months that came with a significant enough size difference that one would clearly be dominate. The larger one was at least 1.5x the size of the smaller and still is. They're both still juvenile I think. They had slept together and stayed in one...

Hello, I just bought a pair of clownfish today from my LFS. I got them home in about an hour and floated for 20 min then drip acclimated for 30 min. I have a bta but it hasn’t been hosted. They seemed pretty much fine but now I’m noticing that the larger female is attacking the smaller male...

I've had two pairs of clownfish in the same 120 gallon tank for over a year now. When I came home from school this weekend, I noticed that one of the pairs fins were ripped up. The smallest one in particular was a lot more ripped up. I know it was definitely the other two clownfish since I've...

Hello. So I have a regular ocellaris clown and a mocha storm clown. The plain OC is larger than the storm. I had them both in my 6 gallon nano reef tank, and long story short I learned the hard way and didn’t quarantine and OC started acting weird for a few days but went back to normal after...

The larger of my two Clownfish has always been a jerk. Often chases away other fish who come near their corner of the tank. Noticed a pretty big gash on her body today. Looks like she got into it with one of the larger tangs. So far still acting normal.

I have a 33 gallon tank with one ocellaris clown fish and a couple ghost shrimp. I Recently added a fire Fish. The clown and fire fish were good for a couple hours but then the clown started dive bombing him. I put the clown on a breeder box in the tank “jail” for a day and a half. I also...

Hi all, About a month and a half ago I purchased a Mocha Storm Clownfish “pair” from my job and ever since then the female has never came around to actually pair up with him. She commonly chases him away, charges and “bites” at his sides, they never sleep together and she overall doesn’t...

Trying to rehome a pair of mocha clownfish in San Antonio the female of the bunch keeps killing everything since she’s become the dominant fish in the tank and it’s gotten problemstic to longevity of the eco system. I don’t know how to ship fish so local meet preferred. Also be willing to...

I have 2 ocellaris clownfish in a 55g. I have had them a little over a month with no signs of aggression. They seem to have become a bonded pair as one has gotten larger and I have seen the smaller one doing those little clownfish dances to the dominant one. I noticed yesterday the dominant...

Hey y'all! I've been wandering if i could keep 3 pairs of clownfish together in a community tank and just how big that aquarium would need to be. Do any of you have experience with something like this? Maybe i could put two anemones on opposite sides of the tank and a third one somewhere in...

Hello there, I am a new member of Reef2Reef and I can not begin to express the excitement/relief I feel to have found a place where I can ask for advice/share any concerns I may have. Compared to my husband I am a noob and I tend to ask more questions than he can answer, I just have a very...

I have a green hair algae problem meaning i have to constantly brush them off. Before my clownfish was fine with it. today he decided to attack whatever i tried cleaning the algae with. how am i supposed to do the maintenance if he doesn’t let me?? does anyone have any tips????

Hello, recently purchased a pair of clown fish. ( They were paired at the time of purchase) along with a sebae Anemone. I have had these guys for about 5 days and just 2 days ago I got them to host the anemone. everything was good up until yesterday and am worried / wondering if I should...

Hey everyone, So I have a pair of Spotcinctus clownfish that I've had for at least 4 years if not 5. They have been with me from a 28 gal to a 55 and In august, they were moved across the country into a 300-gallon. this entire time they've never even attempted to breed despite being massive...

Hi! Just want to check that things are normal when the bigger one (most likely female) is doing it’s submissive dance to the smaller one. I’ve only heard that it only happens the other way round. It’s been a month since i’ve added them and the smaller one stays near the top and the bigger one is...

Hey there! New to saltwater but not new to the aquarium hobby—we have a 90gallon (4 month old) reef tank whose inhabitants are 2 emerald crabs, roughly 6 hermits, 8 snails, and 4 juvenile Ocellaris clowns (2 black ice and 2 bulletholes—they’re orange). We got the original four because they were...

Hello reefers, I need help pairing ( or at least calming down) my clownfish. To give some background: a week ago I got 2 clowns ( from the same LFS, same tank, both ocellaris, one black, one orange). After a lot of fighting (black one bullying orange), I isolated a black one in the breeder box...

Hi there! Over this passed week, my larger clownfish, Amphitrite, has been picking on my smaller clownfish, Poseidon. Because of this, Poseidon started to hide within the coral and in a little cave in the tank. I kept an eye on him to make sure he wasn’t getting too beat up and researched a bit...
