Oto cats, and Ghost shrimp
This is my first time putting tank mates in with a Betta. the aquarium store recommended oto cats and ghost shrimp.
The ghost shrimp are awesome. They are hard to see even when they are out in the open, which is probably why the beta leaves them alone.
The oto cats though the Betta pecks at if he sees them, and the oto's will swim right by him in almost a taunting behavior. I'm wondering how long the squabbles for peaking order will go on, or will the Betta always try to establish dominance?
