A week ago we got 6 Otos.
They have been doing quite well, being little sucky lads.
It’s my first time keeping Otos and from everything I read about them they are the nicest fish and also quite hard to get to eat.
one of my Otos is an absolute jerk.
He hangs out with the Coridoras instead of his own kind and during meal time harasses my poor piggies.
He will take over a wafer (I don’t even think it’s an algae one but a regular Cory wafer) and he will push all the Cories away from it. When they come near, he will sucker to them momentarily and they run away. It really seems like jerk-like behavior.
We put several (4 wafers in - 2 regular 2 algae) in different areas of the tank so no one has to fight. But it’s like he wants whatever they have.
I got tons of algae in my tank (I do not clean the back wall for them) and I add zucchini, which his brethren enjoy. It’s just this one, stirring trouble.
I was searching for this type of behavior and seems that in most threads it ends up being that the person got a Siamese or Chinese Algae Eater instead of an Oto. I do not think that’s my case.
Is this normal?
Just some friendly food competition?
Can he hurt my Cories by suckering on them for a second?
I read that Cories have some venomous spikes in their fins, can they hurt him?
Anything else I can do?
Here is a link to a video of him guarding the pellet. And that’s not even the worst I‘be seen, just did not have my phone near.
Some more of him being a massive jerk https://imgur.com/gallery/htRIgxg
