aggression

Hello all! So a while back I got one of my dream fish, a super young springeri dottyback. Super cute dude, aquacultured, love him. I quarantined him with a Flametail blenny, and introduced the two together into their tank. A couple of times the flametail has chased the dottyback off, but other...

Good evening, I am kind of panicking since I am not sure if this fish behavior/temperament is going to cause stress/death :( Background: 8th month of running a 33 gallon waterbox bare bottom tank with ~25 pounds of dry rock and 1 bag of bio sphere in the sump area. 1 Banggai cardinal added on...

Hey everyone, the hobby has been somewhat of a passive one for me in the last year, but that has sort of changed recently. Anyway, i would love to get a clownfish pair, but I don’t really see the appeal of the usual perc complex clowns. The ones I’ve been really drawn to have been Maroons...

I recently purchased a Long Nose Hawk, A Clownfish and a Cleaner Wrasse. For the most part, everything has gone well except that I have noticed that the cleaner seems to target the Long Nose Hawk disproportionately compared to the other fish for his cleaning service. The Long Nose hawk appears...

We've had a midas blenny for about 3.5 months now, and had no problems with it at all. Super active, interesting fish that didn't seem to care about its tank-mates. Then, about 3 weeks ago we got a blue hippo tang, and more recently a kole tang. Midas blenny keeps biting them, especially the...

Hello all! Ive added a Falco Hawkfish to my 200 gallon peninsula tank, but he seems to enjoy chasing or fin-nipping at my anthias. I don’t have any aggressive fish, just a few chromis, 1 Randall’s anthias, clownfish pair, royal gamma, and a lawnmower blenny. The anthias swims freely but swims...

As the title says, I have a tailspot blenny that was being harassed by my starry blenny pretty consistently for about 4 days. I removed the starry blenny yesterday morning, as I noticed the aggression was not calming down. Today, (it’s late afternoon for me) I come home to the tailspot dead :(...

I suppose "large" depends on what you're use to. I'm just wondering if anyone has specific examples of or experience with tanks dedicated to tiny creatures? Rather than being stocked around minimum sizes, or a mixture of large and small. The closest I've seen are clownfish harems. Half a dozen...

So I just got a new Powder Brown Tang and I was expecting my Six Line and Basslet to bully him, but instead he’s bullying my Foxface and Basslet. I haven’t seen him bully my Six Line and Clownfishes yet (hopefully he leaves them alone. It’s been 5 hours now and I haven’t seen him chase them). He...

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.

Hello! I have a 210, 6’ long with a 4-6” deep sand bed, space all around rock work with sand for them, etc, plumbed into a 60g sump/fuge. currently have: Goldlined rabbit Two spot bristletooth tang 3 x springeri damsels Royal gramma (helped a friend moving) Midas Blenny P. Fridmani (tiny...

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...
