aggressive

So I have two Azure Damsels, I read they weren't quite as bad as the devils. They were buddies, always together. I added three fish, a tang, a blenny and a Dottyback, then one of the Damsels started attacking the other! It was merciless, poor guy couldn't eat; forced to hide up top behind a...

Looking for stocking ideas. Tank is almost fully cycled. Looking for a good mix of fish and live rock as well as possible corals. It's my first tank but I have been around them most of my life. Thinking that I want a semi aggressive or possibly aggressive tank but with color. Any ideas for me...

Hello! I have a 125g reef tank and just setup a 10g coral QT and a separate 29g fish QT. They are separate tanks from the reef tank, but my automated water change process takes water from the 125g tank to the two QTs. (Reef Angel controller is awesome!) Anyway, I currently have a large (3")...

Hey guys I could use some quick advice, or reassurance rather. 90g tank. So I bought a yellow tang that's about 4 inches give or take a little. A week later I bought a Blue Fin Angel who is probably in the 4.5 inch range. Anyways, when I put the angle in, the tang was checking him out and...

hey all! New to the site as a poster, but been following for a while. I just put a new zoanthid frag in my nano tank. My emerald, who has been friendly with all the other corals as of yet, wandered over to investigate. He then RIPPED the newly glued frag, carried it off like a football running...

Hi all, I was wondering about adding a second clown fish to pair with my first (who I've had for about 9 months). The clown is a little snippy - she seems to get along well with the six line wrasse (they always swim together) and sometimes nips at the firefish, but not always. I was speaking...

Is it normal for my clownfish to almost constantly "attack" the other clownfish? I just bought 2 ocellaris clownfish, one a little larger than the other. After a day or 2 I noticed the larger one almost seeking out the other to poke at it. It died after 3 days, not sure if it was sick, water...

I know from past experience that Yellow Tangs are aggressive and territorial. But I'd read on more than one occasion (and NOT in Reader's Digest) that if you put Yellow Tangs in a tank in odd numbers, say 3 or 5, they will school. I have a 180 gallong FOWLR. For the first 4 or 5 days the tangs...

So I have a 90g set up and when I attempted to add a Mccosker's flasher wrasse they flipped out and relentlessly attacked him. They've shown aggression towards new additions in the past when they were in my 20g tank but it was never this bad. I was hoping that would change with their new bigger...

Hello Everyone: So I have a 29g biocube aquarium that has been up and running for about a year. I recently added a percula clown to my tank, she has found refuge in my large frog spawn and is very protective of it. I was looking to add either a picasso or black clown, was just concerned about...

hi everyone ! i've had my yellow tail blue damsel since i set up my tank (about 4 months) and ive just this last week introduced a scooter blennie, a box fish and a bengal cardinal, i also have a fire shrimp in there :) my problem is that the damsel seems to chase the cardinal around the and...

ive had a tank for three years but recently i decided to tear down and start over. my new yellow tang was fine with three chromis, he was never aggressive and only ate algae from the store (on clips) i recently added 2 true percula clowns and a jaw fish and all of a sudden he is extremely...

Hey guys, I have a 300 gallon reef tank that is not heavily populated yet. Last night I added a midas blenny and bicolor blenny, without thinking much about aggression since the tank is quite large and has a lot hiding space. Turns out I was wrong, the bicolor blenny is viciously chasing my...

My smaller clownfish is becoming aggressive lately. The only thing that changed is their diet. I started feeding them bloodworms instead of shrimp. Is there any real cause for this? Its not a particular area in the tank he is defending so I don't think its a hosting thing.

:wavey:Hey I thought this would be a fun post if I get enough people to answer. I want to hear what everyone thinks which corals are the most aggressive in their tanks to the most docile. mine: Chalice, Favia, Acan, Hammer, Frogspawn, Palys, Zoas, Gorgonian, Sponge... Im not fully sure if im...

I have a few tanks ranging from 37g- 150g and im just about to buy a 220g tank. I was wondering if anyone had an idea of what some good sharks are to buy for this type of tank and how long id be able to keep them for before i would have to sell them or get a bigger tank. thanks

I’m in the process of setting up a 210 Aggressive FOWLR. I would like to know if the fish I’ve listed would be too much of a Bio-load for my system, compatible with each other, and which order they should be introduced into the tank. Volitan Lionfish Picasso Triggerfish Yellowstripe Maroon...

I was contemplating on buying a arrow crab because they look like aliens and Apparently eat the strange **** that other inverts don't. Soo i was curious if they hide a lot? Are they aggressive? Do they eat corals or inverts? Hardy? Fast eater? Known to eat other things than common pests...

I have a 29 gallon reef tank with LPS and three small fishes. My aquascaping is like that its hard to get access to the sand. While doing water-change every week I don't like to do aggressive siphoning. If I add sand shifting goby in my tank. Can I do simple water-change without aggressive...

This is kind of a follow up on a different thread of mine. I was thinking about turning that into a reef tank. It would be a 125 with a schooling bannerfish, barttlets anthias, harlequin tuskfish, dwarf zebra lionfish, one spot foxface, blue throat trigger, blue tang, and yellow tank. I know I...
