I did start some seeds a couple of weeks ago and tried to go with bush type plants so I woundnt be zip tieing all over the place. It is a small system, i wanted to start small just so I could see if I was going to get it up running smooth. I have tomatoes, bell;banana; and jalapeno peppers, baby carrots, lettuce, spinach and green beans. And a few herbs taht i am going to mix in. I went to the local pet store and bought 2 dz guppies just to get the bacteria going.. I will take them out later when I get my permanent fish. I was going to go with tilapia because they are very hardy and grow to a good size. One of the main reasons I chose them was that they are an herbavore species. They dont require protiens such as worms or insects like other species do. They thrive on leaf matter and pond plants. I have just started a small 10 gallon tank that I will plumb to the main tank so they are all running on same h2o. I will just keep aquatic plants and am getting ready to purchase some duck weed to fill it. It grows prolific, and all this will feed the tilapia. So nice to think that all of this together just keeps replenishing its self. And once its up and running we will definitely be enjoying it as well. I have done alot of searching for which type of fish we wanted to use and tilapia seemed to be the most hardy and easy. I hadnt heard anything about them being sterile and hopefully we dont run into that. The site from which I was going to purchase from next week, also sells breeding groups. Usually 1 male and 3 female. So I will definitely ask before purchasing that there is a garauntee that they will reproduce under the correct conditions. I am a fish junkie and have had everything from fresh, brackish and salt. So I am confident I can make it happen as long as they are NOT sterile and NOT Genectically Modified.. I am excited to get them in and once i am confident everything runs smooth, I have IBC tanks waiting for me in the garage!!!!
