I've talked to a guy in brandon before that sells live roti's for like $12.
Theyre supposed to be easy to raise if you put the time into it. You just have to keep starting new batches so you can keep your starter going. and then buy the special fertilizer. and keep lights on 24/7 and bubblers lol
so yeah i mean its simple and doesn't take a lot of thought, you just have to keep up with it
