Thanks all for feedback. I too always wanted to play with a large... clowder, clutter, or glaring (thanks kno4te kno4te ) of them and this is my first time.

I have 4 in my ray tank. They are 3.5-4" long and don't school. Each one has its own territory and they don't like to share.
Hmm, interesting... There simply may not be enough of them - the hierarchical domination is not diluted sufficiently for them to keep in school or the gender ratio is not conducive.

Colombian or Peruvian, as asked above, is another good question, although I didn't know that the former get along worse than the latter. Deadliestviper7 Deadliestviper7 tell us more please, where does this observation come from and how often / how many times / with how many keepers is it observed? Does it have a predictive power?

Is your tank heavily planted / furnished? I can't imagine so with rays, they need space on the bottom.

It's a personal observation that I've noticed in hundreds of tanks,over quite a few years,I'm not convicted McDermott entirely that the regular pictus and Columbia s are the same species even,however pictus when placed in large tanks with lots of room and stocked in groups of 14 or more have always schooled in any tank I have seen it done.

When I had my group of 9 in a 75gallon with driftwood and caves. They were always swimming around in a school. Probably cause I kept them with my pair of jags and the cats probably felt intimated.

Jason, you buried your interesting and useful info, so I had to pull it out.

i have 8 in my 450. they schooled tightly in the fairly bare 90 QT but immediately split up and staked territories in the big tank which has lots of cover
