harlequins aren't schooling

hello there i have a fifty five gallon community tank. i recently purchased 10 harla rasboras (about a month ago)to have a nice school but they simply are not doing so! is there any way to incourage them to school more, because they are just spread out throuout the tank and will occasionally school in a grouop of four but then break up...........

any advice?

I doubt you can do anything to make it happen. It's normal for fish to break away, especially if they're feeling comfortable, and they come together at times, but not grouping in a tank is probably normal. Perhaps someone else will weigh in.



Just because animals can't talk, does not mean they should not be heard

Rasbora are generally the most tightly-grouped of the shoaling fish. I have found every species of rasbora--and I'm using this name in the generic sense, referring to those many species within different genera that are now moved into the subfamily Rasborinae--tend to remain in groups much more than other shoaling fish such as characins. However, fish will explore on their own, or in pairs, now and then. The main thing is they are together and know it, which gives them a sense of security rather than stress. It is difficult to say if they will tighten the shoal or not as they settle in to their new environment.

They are not active swimmers as for instance Danio or barbs are, so a well-planted aquarium suits them. The do swim though, they need their exercise too.

By the way, rasbora are not characins, they're Cyprinids [even though stores sometimes call them "Harlequin tetra"] so when I've posted I will move this thread to the Cyprinids section.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

As far as I'm aware fish that commonly schoal will still swim on their own sometimes...

We have some in our 55 gallon community tank and they don't always stay together, I do notice that at night when the day lights go off and just the moon lights are on, they do stay in a group in the same spot every night. I agree with the understand that they are still individuals just like we are in our group of friends, as long as they know they are there they are happy. If you have an aggressive moment from another house mate, you will notice that they will group back up together as well.
