Plausible, I had a jurapari that schooled with some sd I used to have.In the 210 I have a normal SD and a spotted pair of males that school with a Bala shark. I thought that was kinda weird until my little green terror that got left behind in the growth race with the Marakeley and Oscar and started schooling with them as well. Tries to anyway.
Do you think schooling fish can recognise other schooling fish?
Bala shark, that's another fish that doesn't get the love it deserves.
