aggressive

Hey everyone! Many years ago I added a mandarin goby to my 20 gallon not knowing that tank was a bit too new and small to house a mandarin in the first place. It got along with my clownfish just fine in the few months I had it, but recently in my 40 reef, I added a mandarin as I felt I could...

A few weeks ago i bought a coral beauty for my 40g tank. 2 days ago I bought a fire fish. I was planning on getting 2-3 because I know they are better in groups, however the fish store only had one. I put the fire fish in that night, and the next morning i couldn’t find him. I assumed he was...

Getting: Grey smooth hound shark I have a few questions, hoping you guys could answer. 1. How aggressive are they? 2 what, and how often do you feed yours? 3. How much lbs of rock can I put in, and how should I scape it, ex: all on back wall, or piled on bottom…? 4. $500 for a 12” one a...

Hey guys! Today I bought a Lubbocks fairy wrasse for my tank as it’s soon to be a reef tank with peaceful community fish! I put it in my tank and as soon as it was added it was very aggressive very unlike the species, so I thought hey this is I’ll stop after a few hour and 6 hours later and he...

My benggai are probably both males and fighting each other (fluval 13.5). I moved one into a quarantine 5 gal (not ideal) and need advice. Do I add a female, then reintroduce the third? Or add a female to each tank? Thanks coral friends!

Hi there, I have an aggressive Pygmy Hawkfish. I’m having problems introducing new fish to the reef tank. I was curious what you guys suggest? Should I return him to LFS? Or are there specific fish that I should get that might be compatible with his temperament?

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...

This afternoon I went out to my aquarium and noticed my clown tang in the bottom corner where he likes to swim up and down. I happened to see my lionfish was crowded in the corner with him and my tang looked like he was trying to swim forward and back. Did my lionfish get him? If so I know it...

I bought a blueline trigger the other day. He had been moved from one tank in the lfs to another for bullying another trigger. In the new tank he was bullying a clown trigger. Here at home he has been getting along so well with EVERYONE in the tank. He has even blocked a hybrid tang I have...

I am currently looking for ideas and suggestions for my 150g aggressive tank. I so far have: Clown tang Hybrid PB + GR tang Sailfin Dwarf Lion Leaf Scorpion Humu humu Snowflake eel Ghost eel

So I’ve had a bi colored angel for about 2 months now and it’s been fine other than nipping at my Kenya tree which I didn’t mind too much. Buh today I just put in a coral banded shrimp in and later I came back and I see the bi colored angelfish chasing all of my other gosh around. I don’t know...

I’m working on a 200 gallon peninsula and have an existing 4-5 inch blue tang in my existing tank with other community fish that will move to the new tank. I anticipate finishing the build in 2-3 months. I wanted to see what people’s thoughts are getting two Biota yellow tangs now into my...

Would like to gather community opinion on the most aggressive tang they have personally experienced. in my tank maintenance days I have personally witnessed sohal tangs murder an entire tank. What tang belongs in the asylum in your opinion? Even though tangs live and move in large congregation...

I recently added a yellow Goniopora into my 30 gallon AIO tank. I noticed last night that my Royal Gramma was biting at it and I noticed a piece of the Goniopora floating in the water. My question is, will the Royal gramma stop biting it once he’s used to it being in the tank? It’s placed near...

I recently started up a Fluval Evo 13.5g nano tank with my partner. One of the fishes she really wants is a blue damselfish. She seems to like the Starcki damsel the most, but I am a bit wary because even though they are supposedly more peaceful than most damsels, I have heard they tend to get...

Hello guys, I have a 30 gallon tank with a pair of clown fish and a baby Mandarin from Biota. Recently the clowns started to become aggressive towards the Mandarin, he has plenty of hiding spaces, but he keeps getting close to the clowns and getting bullied. Any tips in what to do to get them to...

Hello folks, Got three lyretail anthias today, as part of a buy 2 get one free Black Friday deal at the LFS. They were all housed together with 3-4 others. Got them home, acclimated and such and they were very timid at first, huddled together in the upper corner of the tank- away from the...

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...

After much debating and research, we have finally decided on a tank size for our office lobby. The tank will be open and viewable on 3 sides. Dimensions > 96" x 31½" x 30½" I wanted to go reef, but was overruled by the boss. Aggressive tank, it is. EDIT: This will be a REEF TANK, not an...
