clownfish aggression

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...

I have a very large female Cinnamon Clownfish female I got her from a LFS she was turned in because owner tore down the tank, I've tried to pair her to two different small Cin Clowns and she is semi aggressive but after a week or two she ends up killing or trying to kill the small clown. I...

So I recently posted to figure out what one of my clowns is the female clown and the one that seemed like the female is definitely the male because he just started getting chased around and nipped at by the female why did this just happen so suddenly also now he is at the surface of the water...

I have 25 gallon lagoon mixed reef with 1 sole white lightning maroon clownfish (3” size) I’m not sure on his aggressiveness since I’ve had no other fish with him. How likely or rather unlikely will I be able to introduce another fish or 2 into my tank. I wouldn’t mind trying to make a pair of...

They have been together in this tank for over 6 months. a few days ago I started to notice some fights, but today it's super intense. Is this fight level still considered normal or do I need to remove one of them? https://photos.app.goo.gl/w7mDfYihfxTKWj3p9 Thanks

I bought a 13.5 evo tank with a full set up from a seller than was over the hobby. I made a bunch of upgrades as well and had to handle a crazy outbreak of algae from him. However, this tank came with a pair of 2.5 year old clownfish. I was wondering if I could add another small fish like a...

Unfortunately I think I must rehome my Clowns (Amphiprion percula). They were the first fish in my 90 gallon (Red Sea XL425). They never really cared for my aquascaping efforts at multiple caves and arches, they just bobbed around the corners for months. This was fine. Two weeks ago, I...

Hi Everyone, I recently just bought my first salt water tank from a guy in my area and 2 clown fish. The tank has been running for about 2 weeks now, however the 2 clownfish just started chasing constantly all day today. The seller told me he bought them from a place that had bonded them already...

I have had my 13.5 gallon Fluval Evo AIO for about 4.5 years. I've had a pair of occelaris clowns since starting the tank. Recently, the large (almost 4 inches) female started bullying the male and, I think due to the bullying, he jumped out of the tank. I recently added a small clown and the...

Has anyone ever heard of a Clownfish pairing with something that isn’t a Clownfish at all? Backstory: I had 2 paired clownfish and at some point I bought a single Green Chromis. During the day the pair of clowns and the Chromis would do their own thing, but at night the 3 would rest side by...

Hi everyone Im assuming my female clownfish killed my male clownfish. She was attacking the male all day(Monday) and by the next day(Tuesday) the clownfish was missing. Even though they lived in harmony for 4 months my theory was the male was too small(a baby when I got him) and could not live...

Just an hour ago I discovered my clownfish is not using its tail fin to swim anymore. It is just using its pectoral fins. This is not normal. He is eating fine and he has full color except in the underside. He has ripped fins all alone the bottom of him. Just the bottom fins not the top. Those...

I bought one mocha storm clown fish three days ago today I bought a black snowflake and a bubble chip anatomy they both hosted the anatomy me at first but then the black snowflake started being aggressive with the storm and scared him off what should I do is this normal or could this progress to...

Testing with Salifert and API respectively, my magnesium is 1530 and calcium is 360. Is this normal? Should I dose calcium? If so, how much? My tank is 20 gallons. Also got a male and female cleaner shrimp recently. The female died this morning, wondering if the clowns pestered her too much or...

Dear reefers, Not that long ago I bought a new Orange Stripe Prawn Goby and I loved him. But after 2 days I noticed my Clownfish were attacking my goby, because of that I had to remove the Goby. But now I really want to add a new fish but I don't want the same thing to happen, I know every...

Hello, I recently set up a new tank and added two blackice clownfish. They were friendly with each other at first and now recently the one primarily white clownfish keeps attacking the other. They both twitch at each other here and there but the aggression hasn’t stopped. No damage has occurred...

2 days ago I added a beautiful Orange Stripe Prawn Goby to my 30 gallon tank. After 1 day I noticed that one of my clowns bit his tail but I didn't worry about it because clowns are very territorial. Now at the second day when I got home I noticed anther bite in his upper fin. Now I’m starting...
