Green/blue chromis

Calappidae

Harlequin Shrimp
I got 3 green/blue chromis. I'm going to be adding them to my 125 gallon.

Any advice on them before doing so?
 
quarenteen quarenteen quarenteen quarenteen and one more thing quarenteen Im fighting a big outbreak of ich because I failed to quarenteen one fish lol. Oh also if they are very small best to turn off any powerheads before first introducing them. I added 3 into my main display very small specimens 2 bounced off the rocks so hard they never recovered.
 
Throw 2 of them out. They will fight until only one dominant fish remains.

Seems to vary from tank to tank, I know a few people have had this happen. I started with 7, lost 2 but the remaining 5 have been good for almost a year now. I think they are more concerned with the other tank mates than with each other now?
 
Do these guys play nice with the other livestock? Or vice versa. The setup is a mixed reef with a bunch of little inverts and community fish.
 
They play nice. I have 5 in with 2 clownfish, yellow clown goby, longnose hawkfish, flame angel, azure damsel, royal gramma, flasher wrasse, diamond watchman goby, some shrimp and some hermits and zero isssues

Not only do they play nice, they seem to have a rep for helping bring out shy fish, and mine did do that w/ my anthia.
They often shoal w/ the anthia, the mix of orange and green is pretty nice.

 
While in QT, I treated mine with Furan-2. For some reason, chromis seem susceptible to Uronema, and once that is in your tank, it is there to stay.
 
@ Davocean - Great photo and lovely tank. Just what I am going for now. Building up a 120. Fingers crossed!

Thanks, I hope you have good luck in this as well.
I have seen too many posts that claim they peck each other off to ignore that as a possibility, but then I've seen too many others keeping chromis successfully to agree that is always the outcome.
I think there are other factors we just don't recognize in the split decision on them being kept successfully.
Regardless, they have been a mainstay in my tanks and I don't plan on not keeping them.
I know many see them as a cheap nothing fish, but when you have them and see the vibrating colored shoal it really adds a lot to my tank.
I can't tell you how many times friends or neighbors zero in on them before many of my other fish.
 
I have a school of 6 in my tank that get along wonderfully. They've been together for at least a year now. They school with 2 male lyretail dalmation mollies. Never bother any other fish. They even started spawning about 3 weeks ago. Perfect fish.

I think more people are losing them to uronema then to bullying. Honestly the beginning stages of uronema and the symptoms the Chromis with uronema have shown (at least for the groups I had in quarantine) are very similar to injuries from bullying.
 
They are amazing. So far so good. But who's to say thats going to last long for me..

My only concern is the arrow crab. He loves to just poke everybody with his legs. I constantly hand feed him krill while everybody else gets mysis just to prevent him from hunting everytime there is a new addition or just so he doesn't grab anything in there.

The chromis are the perfect size for him which is scary.. I didn't expect a 3in arrow crab to grow 10 inches in a month (I'm not kidding he molted three times in the past month and doubled his size each molt.)

Are chromis in anyway like damsels behavior wise?
 
Chromis are not typical of damsel behavior at all, very peaceful, I can not say that about your arrow crab, and I would remove him asap.
 
I've had a pair in my tank that have been together for seven years now. They spawn against the side walls of the aquarium, with their eggs making nice snail food. They're quite large now...LOL!
