Thanks everyone. Efors, those Acei are from Itungi. And yes the activity is insane and funny at times. I watched about 6 of the rusties simultaneously do a sand nose dive a week ago. And then 2 days ago, one of the Fuelleborni was swimming INTO the return of the FX5 to graze on the diatoms inside the nozzle. Anyone who has one of those things knows what the flow is like from it:jaw:. My son and I were hysterical watching him, he couldn't keep himself away from it, must've tasted good!
