obv he had a small school or a pair of the parrots and they bred and he just kept the young in the tank.... so thats why there is tons of them.
too bad he is feeding them all feeder fish, obv the guy has no idea what he is doing. He doesn't even know what species of birchir he has....
The small aro looks like it's got it's a$$ beat too, the tail is all frayed.
Hope he is planning on changing the water after this little frenzy as well.... scales and goldfish bits floating all over the tank....
