Hi everyone,
We got a school of Penguin tetras about a month ago (15 in total). We lost one of them to tetra disease but the rest are fine.
My question is why arent they schooling at all? When we first got them they woudl school together very nicely, but now after theyve settled in they done school even a little bit.
I had wondered if it was because there were no "predatory" fish, or larger fish in the tank, as undertsnad that schooling behaviour whilst a natural behaviour is a way of protecting the greater good (i,e they school for protection).
If they are the dominant fish is there no need for them to school?
I have 3 rummies, 3 cardinal tetras, 3 glass catfish, and bristlenose as the remaining fish.
Any thoughts / suggestions??
