we call it elodea normally but anacharis was the old way of saying it i thinkBreed zebra plecs! $200 a pop!
No, really though... Sounds like a plan! Though I'm not sure how lucrative guppy breeding is for selling in the US. In the UK, you just give them away for free on Gumtree (the UK's equivalent to Craigslist) and ask no questions. If you're lucky enough (incoming sarcasm), you'll have someone go "ooh, I'll have that nice one; that pretty one; the one with the xyz tail; the one with the spots" and on and on until you really do think they should be paying you for it. Since they're so readily available, it might not be as easy to sell them as you'd like to think - even the nicer ones. You do have a shot at it though, of course. Breeding is a gamble as is everything else in life, so if you want to take that gamble then by all means do. However, if it goes belly-up, it might not be the most fun or easy to clean up.
As far as plants go, I believe @Sgooosh has his duckweed farm that he's making some money off, so maybe he'll be able to give some pointers on that. Like @Crispii said, guppy grass would be great. Java moss is pretty easy as well! On top of that, you could try amazon frogbit or elodea ...iirc the American term for it is anacharis(?). Again, like Crispii mentioned, some plants may be illegal in certain states and countries, so watch out for that if you plan on selling across states and internationally.
Hope everything goes well, give us updates if you go ahead with your plan(s)!
Hey OliveFish,They bought my EBA back for $10 and gave me $1.33 for each of bloodfins. I guess I am very fortunate!
I have some tips on selling plants,
floaters are the easiest
i'd start with duckweed, salvinia, red root floater, frogbit, or water lettuce
i only sell duckweed n water lettuce right now but once i get a farm going im selling all of them
tip: do not grow small floaters like salvinia and duckweed with bigger ones like water lettuce
it gets stuck on the roots and is a pain to remove every time LOL
i'd really only start with floaters because other stuff like stem plants and elodea people can mass; produce in huge ponds with tons of bio load
something that is not fish related is house plants
you can farm house plants easily inside or outside, and sell it for a good amount
