I keep a green sev and an Oscar together. Put them together as tiny things. Going on 4yrs now. Sometimes the sev decides to be the tank leader, sometimes the O. Regardless, I really like sevs.
I just wondered if it was severus,notatus etc.
I'm not keen on the gold,line bred colour morphs are not my thing but the wild types are all nice.
I would like a pair of mouth brooding sevs one day.
