I was actually thinking of adding Crayfish as a supplement to the fish. The reasons I wanna go with Tilapia is that they are warm growing as opposed to cold and my conditions will be close warm. They are also omnivores, pretty hardy fish, easy to beed and identify sexes, and let's not forget that one of the main goals of Aquaponics is to provide a protein source i.e Tilapia. Yummy
The tank is 100 gallons.
I need some duckweed if anyone has some. Giant form would be great. Very nutritious for the fish but you have to watch out that it doesn't clog up your pumps or valves.
Willy do you know where I can get some of those crayfish this time of year. I should be ready to add fauna in a few weeks when the system finishes cycling.
Pictures of the whole process are coming soon and I have it done in a very simple easy to understand way.
I have crayfish (only a few), and duckweed (not giant form). Richard might have the larger duckweed, called water lettuce; unfortunately the ones he gave me are all eaten by goldfish. Looking forward to your pics! Willy

The tank is 65 gallons. It's still a good enough size for me to start with and upgrading is easy to do if needed.
I've had water lettuce before and it's not what I'm after. There is a strain of duckweed where the round little leave are 3 or 4 times the size of normal ones. That's the stuff I'm after. Plus some Riccia if anybody has some.I'm already calling pet stores around but no luck so far. I'm also looking around for some red wriggler worms to add.
I got lucky and found a source for some Tilapia juveniles and those should be perfect.
Wow, that's quite the serious set-up! For your aquaponic system the floating plant that you're looking for (I think)is called "frogbit". Check out Craig's List. I found this in Vancouver's CL. vancouver.craigslist.ca/van/for/5782732788.html Cheers
