Hi Folks!

I'm looking to raise both azolla caroliniana and feeder guppies in my (2) 75 gallon DAS. Both flora and fauna are destined to be food for my flock of ducks. I'm thinking of putting the tanks in my greenhouse which maintains a 70-80 degree temp during the winter.

Should I cycle the tank/filter, let the plants establish, then introduce the fish?
Do you think additional lighting is necessary beyond the sunlight?
How many gups do you advise I start out with in 150 gallons?

Any other tips would be appreciated
