Liveaquaria is wrong. Minimum tank size is 55 gallons for 1 Sev IMHO. I do have 2 Sevs in a 75 gallon. Mine are buddies, possibly a pair. I have some Tinfoils I need to move out of there to the pond we are building. Currently I am filtering more than double while I get it all set up. In the near future these two will be housed alone in the tank and we will see what happens. You could skip on the Severum, but I do highly recommend them and just one will not bore you....they are very personable.
