Alright, so I've had this little Paradisefish, I'm not sure of the sex, in a 5g tank, but two nights ago the tank decided to quit its job so I put the Paradisefish in a big rubbermaid crate, slightly larger all around than a 10g with a muchbetter width to height ratio.
I know Paradisefish are pretty aggressive, hence why I'm asking before I throw a random fish in there.
