Do you think that aggressive behavior will be on display if I move him
from his home into the larger tank with other fish it is not used to
seeing? With fish that are curious and playful (yoyo loaches) and
fish that tend to hang out in the same area of the tank (loaches,
pleco)?

Any comments are welcome. Thanks.

My understanding is that when golden algae eaters (Chinese algae
eaters) are young they are fairly passive, but they become aggressive
as they mature. The size of the tank may have some bearing as the
mature algae eaters' aggression is likely linked to developing
territorial-ness. A larger tank may reduce territorial stress. Being
pestered by tank mates will not. As the algae eaters' dietary needs
also change as it ages, I have heard that ensuring that it is well fed
(not just left to find algae on its own) will also minimize
aggression.

Good luck!
