aggression

Hello, I have a 126 gallon cycled tank ready for fish. I understand that aggressive fish are added last as to avoid them becoming bullies, but what about fish that seem to have variable temperaments? From what I read, something like a clownfish can be aggressive or calm, while royal gammas tend...

I introduced my sapphire damsel AFTER my 2 clowns and AFTER my clean up crew. Then I added a foxface rabbit AFTER the damsel. Now I recently caught my damsel chasing my female clown and now it's trying to intimidate the foxface. Should I remove the sapphire? Here's a video I managed to catch...

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...

Yesterday, I got a QT'd midas blenny that I had in an acclimation box overnight and none of my fish paid attention to it. This morning, I released it into the tank before the lights went off and my starry blenny is going after it. The starry blenny is significantly larger than the midas blenny...

My big clownfish had the little fish in its mouth but couldnt eat him. What to do? I have the little one in a breeder box safe.

Hey Reefers! Over the weekend my LFS had a customer appreciation event where a few different pairs of fish, assorted gear and in-store credit were given away. I happened to win a set of Lightening Maroon Clownfish. I have an empty but cycling 65 gallon tank that they will be going in. They are...

TL;DR loss of fish brings issue of peaceful additions near aggressive six-lined wrasse, how do I deal with the aggressor? Is it better to rid myself of it? Hello all, I recently have run into an issue where I am attempting to add a late addition to my tank after the loss of two flame angels (not...

https://youtube.com/shorts/FrzrSiFdixo?feature=share Howdy! The tank is nano 15gallon fluval. All cycled. When I first got them, I did not know what species they were. As I have researched I found that more orange in the eyes is a perc and more black is an occy. I am pretty sure the larger...

Hey guys so I wanted to know before I make the jump but I’ve read on LiveAquaria that the pink tail is aggressive but how aggressive are they? I currently have a blue tang (hippo) and a chromi in the tank theyre small like about 3in so they’re small and I’ve been eyeing this trigger for about a...

Hey y’all, This is not a fish disease related post, but it is related to quarantine! It’s been awhile since I’ve been on R2R, but I need some advice. I’ve had my clownfish for about 6 months now(alone, not pair), and want to introduce a male. My quarantine procedure includes copper for a month...

So I got my first clownfish a couple months ago, and special ordered a a black ocellaris that was not in stock. Then I found out about QT’ing fish and asked my LFS if they could hold the 2nd clown once it came in until I can get a QT tank set up. well LFS called me today informing me that they...

I picked up a forktail blenny recently and while his first couple days were relaxed, showing no aggression to anything. Today at feeding time he suddenly became aggressive. He ignored the food, even when dropped in front of him (both pellet and flakes) and started hunting (and eating) the tube...

I really fell in love with my Neon green Leptoseris so I got another small frag of Jack-O for $100. I feel like they’re really rewarding as a beginner SPS because they grow fast and are pretty hardy. I want to collect more morphs of Lepto and I was wondering if Lepto can be in close proximity to...

I hear about wrasse aggression, especially in regards to other wrasses, obviously I hear about this after I bought a 6line. Then I look into wrasses and fall in love with the look of two, and I'm trying to do my due diligence and actually plan these out as best as I can. I'm looking at a white...

Hey all! just finished the new 400 build. Lots of rock, lots of Tonga branch/plate, and lots of aggression from what we’re happy healthy tank mates for past 14 months in a 230g. background: all tank mates were in a 230g. Had a bad breakout of ick and broke the group up into 3 separate tanks...

Hi all! Happy Weekend! currently I have a Purple Tang and a Foxface. They get on completely fine but like brothers sometimes do want there own space. I was thinking about adding another yellow tang. would a third calm aggression or would it spike some more trouble? currently a 200 litre tank...

Hello everyone. I was wondering if anyone had any experience with Tangs being aggressive towards eels? I purchased a 16' Zebra eel two weeks ago for my 80g (48x24x17) and ever since the first day in the tank my tang is constantly beefing with him. He will swim into the cave the Eel likes to hang...

hello everyone, I am researching clown gobies and would love to put a small group or pair in my 20g long, but I have heard conflicting information on putting multiple in, my preference would be multiple or a pair of yellow clown gobies but if I need to get different species I will. Just looking...

I have 2 clownfish and a marble/checkerboard/hortulanus wrasse in my 125g. Wrasse attacks clowns when food is dropped yet, wrasse won't eat it. Clowns are confined to the top of the water or the corners. The wrasse always watches them. The clownfish don't fight back. I feel as though I should...

Hey all, I'm not sure if my fish are having aggression issues or if this is normal behaviour. Any advice is appreciated! I recently downsized from a 24g to a Fluval 13.5. In it I have plenty of live rock with many crevices, tunnels, and hideyholes, my corals (mostly small except for a "large"...

1 - my rock work is a series of caves and pass through, getting a problem fish out will be difficult even with a trap. 2 - Currently have 1 blood orange clown, one ocellaris (took about 10-12 days but they are best friends already thankfully) & a Midas Blenny. 3 - 75g, 4’ long with a 40g breeder...

Hi everyone, I am a tank caretaker at our college and we have this interesting case I wanted to share in case anyone recognizes it. This female clown is in a 30gal SW tank with a purple dottyback. Other inhabitants are really large toadstool, CUC (urchin, green emerald crabs, hermits, snails...

So I’ve had 2 clownfish in my tank and every fish I’ve tried to put in there they have died and I’m pretty sure they killed them maybe just the black one she’s kinda aggressive. I know they can be territorial if I put them in a breeder net for a bit and add another fish to the tank would that...
