20 long as a quarantine and hospital tank?
I just broke down my 20 long, put the swordtails in my 75g, and am trying to decide whether I want to use the 20 long for a quarantine/hospital tank or just buy a 10g for that purpose and set the 20 long back up as another tank. I tend to keep common fish, and most I get in are small when ordered. The only larger fish I would have to hospitalize would be my angelfish, and where the height of the 10g and the 20 long are the same, there would be little advantage to the 20 over the 10. Maybe try to find a 15g or 20 tall? Am I worrying about nothing? I like the 20 long format as a display tank. That's how mine originally went from a quarantine tank to a display tank.
A couple more questions about quarantine/hospital tanks. Do people keep them running constantly or just when needed? If only when needed, how do you deal with the nitrogen cycle? Seeded sponge from another tank?
