Oh my gosh - they school!!!

[Angel*Fish]

I'm sooo thrilled!!!--:rollface:
I bought 9 little Apogon something-or-others & they stick together in the tank like glue. I think they are called bluestreak cardinals.

Not the prettiest fish in the tank, but they make a fabulous display. I highly recommend them to anyone considering it!
[Please note I've had them < 24 hours]

sounds cool, it's hard actually finding fish that will truly school.

Are these the blue-eyed cardinals? If they are, then yes they do school. Expensive little buggers but very cool to watch.

Those that watch Yu-Gu-Oh - I name them blue eyes white dragon (heh-heh)

Raddogz,

Do they definitely always school? I've really ben trying to find some smll schooling fish. Are these cardinals my best shot? How many will I need? I was thinking I'd get 5 or so.

 

[FishF00d]

I think she is talking about the threadfin cardinalfish. One of the few that are more commonly available that school. I noticed them on some lists this past week and they are also being sold as the Glass Cardinal I believe.

I think they are the same or very close to the same - they have less blue than some photos I've seen... Why they cost so much is a mystery to me... one fish , no big deal but x 9 is kinda high, for me anyway. And it looks like only 7 are going to live - two came with too much lost from the tails fins Someday I'll learn to bring my glasses to the LFS.

I'll post a photo as soon as my daughter locates the camera ,

They hang together in a very close group -- at the LFS they caught them all at once together in one container (They didn't disperse) They don't swim around all over the tank - but they are always reacting to tank events & I have enough fish to ensure plenty of things to react to They seem to prefer being up in the water column.

Do they look like this?

 

[c. dawg]

Blue-eye Cardinals, Glass Cardinals, and Threadfin Cardinals are the same species. The picture above is what they can look like (or better) depending on the lights they are under. When I bought mine, I could hardly see any blue on him at all. When I put him under my lights he turned blue and had red on his dorsal fin.

Yes I think that's the fish - only they're much smaller

Chromis are also schooling fish & the green chromis are pretty common & cheap, sometimes they are more blue than green.
I believe some damsels school also.

 

[sandlot13]

ive heard that most likely its not so much schooling that occurs in small tanks, but more so just common interaction in an area they all like. Most likely thats whats occuring with your fish as well, but thats just my opinion. some pictures would be awesome though

The way I understand it is that they they are shoaling fish which is a term commonly used to indicate a dominance hierarchy. In the confines of an aquarium this typically results in the weakest fish being bullied into decline & resulting death. When that fish is gone the next weakest is picked on --and so on..

As sandlot13 mentioned most of those fish generally stop hanging out together as they become more confident & establish their own territories in the tank.

These little cardinals I bought are thought to be different from the above & so far "schoolers" they seem to be. It's only been a couple of days though.

Sorry still no photo - only 7 left now & and a couple have something that looks like Brookynella or something :eek1: I may have to add some more later. I should have quarantined them - it's stupid but I just forgot to.

 

[raddogz]

Granted I am down to two at last count (were three), they schooled

 

[Angel*Fish]

Finally a photo - it's a little too blue - You can clearly see the huge sore on the fish near the center The fish just below him has some problems also

raddogz, did you observe any aggression among them?

 

[AIMFish]

I think these are the ones ORA is breeding now. I usually keep Pajamas and Banggai together, different tanks same species, and when the numbers get low 3-4 they do seem to get a little meaner on each other. I just went to their site and they are different

Marie,

be aware that tjey often dont ship good. Toi be honest yours look like trouble comming. They are the thin and to pale. Check carefully for any sign of white pop or of the transparent part gets whitish.

I would recomend UV and starting to feed enriched BBS.

BTW, when they are adult and there are no predators all cardinal wont school.

 

[Angel*Fish]

Thanks Peter, you are right on target One of the hazards of buying a fish you're not familiar with is not knowing what a healthy one looks like. From the look of these fish this morning, I would not be surprised if not one of them survives.

The one in the photo with the visible sore is dead now of course. Another looks just like the dead one did yesterday.

I've been feeding them them just hatched BBS from the beginning as I have one other fish that will eat nothing else anyway mixed:

Your statement re: schooling -- BTW, when they are adult and there are no predators all cardinal wont school.
In your opinion could an active angel tank containing an aggressive man-eating bicolor anthias qualify?

And if they don't school as adults will they kill each other?

I don't own a UV - do you really think it could turn things around? I can buy one.

.the transparent part gets whitish.

That's exactly what's happening - 2 had it on the caudal peduncle & 2 in the center of the body I mostly assumed it was a shipping injury that was confined to the 2 fish I first saw it on - is this a disease?

Hoe did you guys get tetras to live in your reef?

Seriously, I have seen those tetras shoal together for years. They don't school, but they stay close to one and another and move around in groups. The dude got 20 and ended up with 10 or 12 of them. This was about 10 years ago when I was in college.
