Blue/Green Chromis info

[LUVSPS]

Hi, everybody! I am looking into getting a small school of blue/green chromis for my 120 sps tank. I have read that they will slowly pick each other off one by one. Would that be a problem if I get 10?

What has been your experiences with them?

Also, do they slowly change color from whitish blue to a deeper pretty blue? Sometimes I see really light ones sometimes I see deep blue/green ones. Is there that much of a variation?

I have also seen the Blue Reef Chromis and I like their color better than the Blue/Green. Are there any differences in personality? Would a school of 8 or 10 be fine for my tank?

What should I go with, Blue Reef or Blue/Green? Sorry for so many questions!

Thanks in advance!

The typical blue/green chromis that you see can change color based on their current mood or the lighting they're under. There can also be a bit of variance when they grow. There is a dark blue type of chromis (check liveaquaria) if you like a deep blue. Rumor has it that if you have a group in a tank with a ton of flow (like your SPS tank?) the fish will shoal and this can possibly prevent aggression.

On live aquaria it says that the Blue Reef chromis get to be 5 inches. Do they really? Would they look to big or would it be too much if I got 8 for my tank? I would really prefer to get the darker blue ones.

Thanks for replying!!

I have never had the blue ones but the green chromis pick each other of from my experience. I have heard that the blue ones are more peaceful tho.

Odd numbered schools seem to do best in my tank. I love my blue/green chromis -- they seem to glow a nice electric blue color when they're happy. Once they establish a hierarchy and find a secure place to sleep, they'll stop chasing each other and swim and school together. Mine seem to eat anything and are great to watch because they are always out swimming. Had mine 16 mos. and thy are still 1-1.5" long.

How many do you have?

I started my tank with seven blue chromis. I lost one after 2 months and have had six in the tank for over a year. They get along great. I haven't had any problems with them picking on each other, but that's only my experience. Good luck.

I had some die over time and then a group stay very stable at same number of fishes.

I've had 7 green chromis in a 55 for about a year; moderate flow. My male lyretail anthias chases them, and IMO, that helps to keep infighting amongst the chromis to a minimum.

i have always read and been told that if kept in odd numbers you will never have a problem, and on this post someone seconded that too!

 

[LUVSPS]

Thanks everyone for replying! I have decided on 9 blue/greens.

Now if I can just get my tank set up

 

[mhills16]

i have 2 in another tank and let me tell you, one of them is killing the other and is very horribly aggressive! he will surely be dead by tomorrow , and this has been going on for 3 weeks, and after he dies i doubt i will be able to add any more! so, goes to prove the point also!

I have never heard of a school of greens that didn't require new additions on a regular basis. In our sale tanks we either have to pack them in tight or split them up 2/3 to a tank.

Blue reefs I have never had or heard of a problem with, amazing fish

 

[LUVSPS]

Wow^^ If that is the case then I think I want Blue Reefs. I certainly like thier color more. I just worried about thier size. I have read that they get bigger than the blue/greens. Do you think I can keep about 9?

Thanks for all the input!! I Love RC!!

I ordered 5 bg chromis from the doctors for my 180 gal and they sent me 6. They picked each other off till down to 3 left now. The alpha seems to be very aggressive toward the remaining 2 especially at feeding time. We will see if they last but they did whittle it down to an odd #.

 

[agreeive?fish]

I dont know if the odd number thing really works with chromis... i started off with 3 in a 210g and after 2 days i had 1..and the other 2 had obvious signs of combat... and the survivor is a mean little fish... he will attack the ~ 6 inch asfur with no fear

 

[LUVSPS]

Anyone else have experience with Blue Reef Chromis?

 

[nauticac4]

I am a firm beleiver in the odd number thing. I have had 5 for a little over a year now and not lost any (knock on wood). I plan to add a few more probably bringing the number to 9 total.

they do get into quarrells every now and then but I think they are evenly distributed across the group.

I also find that feeding a good variety and often makes for the best colors in them. When i got mine they were pale and now they have that nice blue green with the bluer lines under the eye and in th tail.
