Small Schooling fish.

Firefish always hang out together when you have a lot of them

Over time 2 pr off and kill the others in aquaria most of the time.

I have had 5 in the same tank for 2.5ish years now guess ive been lucky this far lol I had no idea they would kill each other off

Most of the time I see it attempted it doesn't last nearly that long. It's good to be lucky.

I was wanting a school of cardinals... looking at several different varieties. Walked into the LFS, someone had traded in 4 adult PJ cardinals. Big, fat, and healthy. $5 each, if I bought all 4. Well... that's my school

Not the most attractive fish, perhaps, but they do stay together, and they're model reefing citizens.

To me though their color makes them unique with their orange eyes, polka dots and yellow/green under chin. My wife really likes them. I only have a single one (he is an ORA Captive Bred) but he loves just hanging out in the tank and was the one fish my Yellow Tang and Coral Beauty Dwarf angel didn't pester at all when they first got into the tank.

What about Ignitus Anthias?

I’ve had blue/green chromis for a couple years with no issues. They add nice color and are easy to keep

'All breed regularly. no 'real' fighting. 6' 2'wide and 20" deep reef.

 

[psidriven]

if you can get them, mini dartfish school very tightly. they do hide in the rockwork from time to time though and you'll think they all were eaten.

The best way to get chromis schooling imo would be to recreate thier natural environment. 30 seems like a good number but if you can get up maybe like 50 it will be even better. This will require a huge tank. Then use acropora as a source of shelter and add big fish such as tangs to intimate the smaller chromis. Perhaps add a few large aggressive damsels too for a more hands on harassment of the school rather than intimidation. This will cause them ti school and not attack each other. Constant feedings will help as well.

I'll say it again: fish don't school in captive tanks, regardless of how large. They may schoal together, maybe, if they feel threatened, but even that is iffy.

 

[rosshamsandwich]

get tetras if you want schooling fish

I’ve had good success in the past with Bangaii, I started with a single female and two males and within 2 years had 22 all from the original trio. The males held there own territory and were not in eye site of each other. The juveniles shoaled till adult size then established their own areas of the tank.
The female would take it in turns to get the males mouth brooding, once he had a mouth of fry she go in to the next, she was a smart lady and the boys got a breeding break while she cheated! Lol
I’m planning on keeping Bangaii in a 300l mixed Bubbletip anemone tank, with longspine urchins again....another side project but sharing a sump.

That's awesome! What size tank was that going on in?

I had 6 Chalk Bass in my one tank. They seemed to get along and would sometimes hang out together. I’m putting in a 130 and a 260 gallon tank. I’m thinking of getting 20 for the larger tank and 10 for the smaller.

6x2x2 so pretty good size.

 

[Makers Marc]

Hate to be the bearer of bad news, but no fish will school in a tank. Maybe they'll hang together every once in a while, but that's about it. The best way to have even a chance of them schoaling is to have a large tank, put in a whole bunch of small fish and intimidate them with a few big ones. Then, maybe.

So what percent of the time do your resplendent anthias shoal together? When they aren't shoaling, are they hovering far apart from one another or still in the same square foot area?

I was expecting you to say larger than that, how did it end? I assume eventually they would run out of space and the adults would start going at it.

Nope, never had a issue. There was a lot of rock work so line of site was broken up.
