Black Axle Chromis

Pretty convenient considering they also cost 4x that of your run of the mill blue/green :rolleyes: Their behavior is typical to most other chromis species, and no, I don't at all believe they would have a greater chance of mingling with each other in captivity long term
 
I have heard people say they don't pick each other off. Is this reliable info or just an experiment?

My experience, for what its worth, is that chromis (blue, green. or blue reef) is that they are territorial and aggressive. I bought 6 blue reef for a 180g on the recommendation that they were peaceful...what a joke. I was down to three in a couple of days.
 
I had a feeling... Your username means I should trust you for sure right?!?

Any suggestions on some high tank schooling fish?

Longspine cardinals (Zoramia leptacantha) (I would avoid ordering them online, they don't always cope well with shipping stress), zebra dartfish (Ptereleotris zebra), Resplendent Anthias (Pseudanthias pulcherrimus), Chalk Basses (Serranus tortugarum) etc. All of these fish will readily coexist together in groups, just be sure to feed small amounts of food, multiple times throughout the day (specifically for the cardinals and anthias). Good luck :dance:

Yep, IME blue reefs are some of the worst when it comes to conspecific aggression. Beautiful species, and I wouldn't mind adding one to my 120g, but I'd never bother trying to house a group.
 
I have kept Black Axil Chromis in groups on several occasions and for several years without issue.

There are many species of chromis. Some will coexist well together, some will coexist for awhile together, and some will fight each other aggressively. I have found the black axil to coexist well.

Also, whenever I look for the black axil I find them for the same price as the regular green chromis, not the 4x price as stated earlier.

I agree.

In my area, and online at least, black axils always fetch about $15-20 each, whereas small blue/green chromis typically cost $3-5. How many in a group have you kept successfully and in what sized tank?
 
I have kept 6 in a 150 for 2 and a half years and 6 in a 5' 100 gal for around the same. There are 2 males in each tank that on occasion spar, but not for long.

Recently I lost 1 in each tank, each was the smallest of their respective groups. I do not attribute it to aggression, but rather social rank related to lifespan. In any social system there is a heirarchy, where over time the difference in resources that the alpha receives verses a subordinant catches up and results in a shorter lifespan for the subordinant, but is still within the range of a "normal" lifespan.

Ah, very interesting. Have you noticed any other inherent differences in the black axils versus the blue/greens?

Nothing outstanding, I just find that they last as a group longer than a group of viridis, though with viridis I have found there to be a true "pecking order" where there is a definite low rank that is always a little beat up looking.
 

IME Ochrestriped cardinals don't actually school. They're similar to the banggai in that there will sometimes be 1-2 pairs, and then whoever stakes out a territory far enough from that of the existing dominant pair/s. The rest will usually be killed off pretty quickly. Cool looking fish though for sure, I just have never known anyone who has successfully kept a true school of them.
