Last week we went to Chincoteague. While there, the kids and I went exploring along the water and caught (then released) many cute little creatures. One of them being shrimp. It got me thinking that I might enjoy adding some freshwater shrimp to one of my tanks. Would it be OK to add some shrimp to my 29g? Currently home to 3 giant danios and 9 female platies. The temp hangs around 80 (even with the heater off). 0 ammonia, 0nitrites, pH is set at 6.0, and nitrates are still a bit high--like 60ppm. I have gravel substrate, live plants (java fern, wisteria, swords), and caves. 30-50% water changes and gravel vac once a week. If I could add some shrimp, how many and what kind? What else would I need for them? Thanks.
