Blue green chromis

[Bthomas]

I've been wanting to get either a group of anthias or blue green chromis for my 150 gallon. I had pretty much decided on the chromis because of the price (I like the look of both) but I've been reading alot about chromis not getting along with each other.

Anyone have success stories of keeping a group in a largish tank?

My second choice would be a group of dispar anthias but at 30 bucks a pop that's a little hard on the wallet..

I had maintained a school of 40 tiny-small blue green chromis. Six months into it, I was left with 24 medium-large chromis. Currently, I have 4 extra large chromis left. They do bully each other and the ones that are bullied slowly starve to death.

I agree with yellowfin. While I never had 40, I have tried adding a few at a time and it always winds up the same, one or two out of a handful etc

Aw that’s to bad. I have 1 right now I was thinking of adding some more. He’s so cool for such a little/affordable guy. If you do add more is there any luck with introducing a certain number every time? Like some fish are best in groups of 5 or 7; usually odd numbers.

 

[YellowFinsReef]

There's no luck with any certain number. Most folks usually end up with one.

This is disappointing

I've had groups long term several times, 6 for 6 years were my longest run and only lost them to equipment failure during a swap.

I have 6 right now in my 120g, little over a year now, no issues.

I actually keep green chromis in every tank, and I keep different anthias w/ them as well.

I do see a lot of these posts saying it is difficult to keep them, but I also see and know a lot of other reefers that don't seem to have a problem either, so I'm not sure what's up exactly.

I think many times they are shipped poorly or come w/ disease, uronema being very common, also common in anthia, so both fish should be QT for sure before going in display.

I have had a group of 8 now for over a year, maybe closer to two, not sure as I would have to check the pictures. It will work out if you get a single dominant fish to start IMO. That keeps the fighting down, won't stop it all, as there is already a "king".

A pic or it never happened.

I always get them as small as possible, just my preference w/ most fish purchases, I like to watch my fish grow over time.

These are the 6 I had 6 years, their size compared to tang gives an idea of age.
These were in a 180g, but I've had groups in 150's and 120's as well.



Mine also tend to group together w/ my anthia groups pretty often as well, this is in a 150g

Exactly what yellowfin said above. I had, I forget if it was 3 or 5, in my 150gal. For the first year I thought I'd be different than everyone ending up with 1. Then a few months later they spawned so I thought great! Then within a week or two the domanint became a jerk. One went missing only to turn up months later. The other went into hiding on the opposite of the tank as the dominant and eventually ended up in the overflow were it lives because I cant get it out. Tried everything. I also feed extremely heavy which I thought would help but I guess not enough.

I’ve kept 3 in my 60g with 10 other fish. The 3 chromis are great eaters they do bicker some had them 7 months I do feed everyday. Dustin

Well I just returned from my lfs where I picked up 6 chromis so here's hoping for the best.

Is there anything special I should know about quarantining chromis? I just read on another thread not to treat them with copper?
My usual protocol is 2 rounds of prazi and then 30 days in copper
