Number Of Smaller Tanks Housing Different Species

[alphabetic]

Do you own a number of smaller thanks (ie < 30 gal) housing species of fish in each, with different setups (ie. a shoal, centrepiece and bottom dweller in a planted tank or perhaps one larger shoal only in another, comprised heavily of rocks/driftwood etc. A collection, some might call it.

Did have two community tanks, both in 19 Gallon tanks. It worked fine.
