Oh, I have shrimp. Mine are near zero care opae ula; I top off the tank with distilled water occasionally but that’s it. Well, and I have them on a light cycle so the algae grows.
Still, if anyone is interested or feels like shrimp would improve their lives, feel free to respond and I can help set up a new tank. Mine are truly near zero maintenance though so I don’t know if it would be a profound life change like OP’s.
I got my original ones from this unethical company that put them in tiny sealed enclosures. Well, from a gift shop that was selling them. When I realized how unethical it was later that day, I made a quick plan to break them out.
I’d recommend getting them from good breeders. There’s an eBay seller GotSnails who was, when I left reddit, a large contributor. Messaging him on Reddit was cheaper than the eBay store back then since he’ll just send an invoice. There’s also the supershrimp store.
They do breed in tank conditions! My original ones bred after the breakout. It can take a lot of time and some work making sure your conditions are good, but mine didn’t require anything.
All I did was get:
They’re a lot of fun and I highly recommend it. Feel free to respond if you have more questions or want specific links to what I’d do if I was starting afresh. You can choose from any ethical seller though.
