aggression

Looking for advice from Bundoon blenny owners, I purchased a trio from DD 3 wks ago. They went into a 30 gal observation tank as 3 hungry pale buddies. I’ve been trying to fatten them up before release into a 150 gal reef tank. Feeding 4-8 times a day (pellets, LRS and ROE). 1 has colored...

I have a few questions about MiniMaxi Anemones. How are they towards coral? Will they try to sting corals that are near them? If they were to sting a coral, or go to war with one, how would it turn out for the anemone and for the coral? Has anyone ever lost any corals to Mini Maxi aggression, or...

Hi guys, I have two ocellaris clownfish. One black/white and regular one. Black is smaller and always being attacked and trapped in the corner.I have never seen him vibrate. The aggressor sometimes vibrates. From what I have read the black one should eventually start submitting and the...

I picked up a fire fish for my 55 gallon about 3 weeks ago now and for the first few days it mostly hid. Recently it has began moving out of its hole more and has become the center of aggression for my coral beauty and female clownfish. They will both take turns chasing it around the tank. Last...

I added a Rusty Angelfish to my tank but my normally timid Lawnmower Blenny doesn’t seem to enjoy the new addition. Any thoughts on reducing the aggression towards the angelfish? Also feel free to post other aggressive or strange Lawnmower Blenny stories.

Hi, I have a mid-size Davinci Clown that I've had for about a year who was one of the first tank inhabitants. About two weeks later, I got a much smaller Black Ice. Up until a few days ago, (so for almost a year) they got along well. No bickering, shadowing each other, and only co-hosting a...

So I bought a 4 or so inch harlequin tusk - who is friendly - healthy and beautiful. He doesnt do any of the 'bad things' that they are supposed to do - he doesnt kill shrimp, snails, crabs, etc. However - he and his beautiful blue teeth when he expects to get fed - literally attack he will...

Hello! I've got a male McCosker's Flasher and a Firefish in a 20 long tank. I love them both to death and they have got along perfectly fine for the longest time. Occasionally during feeding the flasher would flash a little and show off, but the Firefish seemed unperturbed... until now. The...

Hello, I am running a 75 gallon reef tank and have recently added a juvenile Kole Tang to my current stock list which includes two ocellaris clownfish, one banggai cardinal, one fairy wrasse, and a sand hopper blenny. After acclimating the Kole it took quite well to it’s new environment. The...

Last week I noticed a small strange mark on my one spot fox face that I have been keeping an eye on ( I tried to get a picture for 15 minutes and can't). Since then, a 2nd and 3rd mark has appeared, which appear to be bite marks or scratch marks. I haven't added a new fish in almost 2 years...

Hey gang, I just had to pull my White-Tailed Bristletooth tang out of my tank since he decided he hates wrasses and gobies after a couple of months. I was pretty dumbfounded as to why he would be aggressive towards fish that aren't grazing competitors, but have no problem with the other grazer...

Hello folks, Looking for some advice. Recently purchased 2 tangs, a yellow and a kole. Bought them together, acclimated them together- they are besties. Problem is my fox face. Had him for several months before getting the tangs and he is easily twice their size, but he is the shyest fish I've...

My whitetail bristletooth was bullying my Midas blenny. So I bought a fish trap and kept watch. The Midas is hiding so now the bristletooth is really aggressive. It is like without the blenny, he is amping up the bullying more. He is leaving my other tangs alone. But today he started going...

Hi All - I added a new clownish (1-1.5 inches) to a 75 gallon reef that has a yellow / blue tang, flame angel, clownfish, melenarus wrasse, and six line wrasse (they have been in the 75 for about a month). Immediately upon introduction of the new smaller clown I noticed that the six line wrasse...
