I've kept Red Cherry Shrimp for over a year and half. I've sold tons of them to states all over America. I also have a Blue Pearl/Blue Rili/Velvet/Jelly/Whatever project that's about four months old and doing great.
I had OEBTs at one point, but the new place I moved to had old copper pipes unknown to me until after almost all of them were dying. Last month, the last one died off. I've since started using alternate water for my Neos. They were able to survive. I plan on moving in February, so the copper thing won't be a problem, hopefully.
Thanks for the advice. I think I'd like to try the Super.
