iClown,
You will surely find someone out there if you look hard enough but when you do, just consider how long they were able to maintain it and what measures they took to keep it alive. I do have a friend who kept a RBTA and a pair of tomatos in a ten gallon with a clay flower pot, a heater, a strip light and a bio-wheel for filtration for a good six months and it did live all that time, but he had a lot of experience as a reefer/breeder and I really don't know if it eventually died or if he moved it or what. I'm just saying that I and probably a few others would advise you to just add a couple softies that are known good substitute hosts.
duncantse,
Fish much?
