Hi Silverfighter. in a nutshell
Depends of the type of shrimp you plan to keep. The 2 common shrimp are cherries (yellow, reds etc) or Taiwanese bees (CRS/CBS etc), with cherries being the easier of the 2 to care for.
Eat- bottom feed, algae, vegs bio-film
Filtration- dependent of number, but shrimp produce minimal waste when you consider a fully grown cherry is approx 30mm. I uses internal sponge filters
Air stone- hot weather , water agitation is key
Plants- moss for juveniles
Read, read, read,
Water perimeters (WP) is a topic of much discussion, some uses untreated tap water, others us RO water. pH 6 - 7.4 .
Try and match your WP, with the person you buy your shrimp off, if unsure, slowly drip acclimate. People talk about keeping Red cherries in a bucket outside, no air supply, heater, etc. As long as you keep then below 30 degree you be fine. Shrimp do better in shrimp only tanks, all fish will eat shrimp or their babies.
