Blue Tigers, like many caridina species, prefer softer water with a lower PH than neocaridina species. You might have a difficult time keeping blue pearls with them.
True enough; it's certainly possible, but perhaps less than ideal. Water with a PH around 7 and a fairly low GH / KH might be a good place to start.
I can't keep any tigers, CRS, or anything like that because my water has a PH of 8 (And I'm too cheap to buy a booster pump for my RO system).RCS and Malawa, on the other hand, love my water.
That process of stabilizing your pH seems like it could get fairly complicated, lol. I also have the same pH problem; this week it tested at 8.2. For now I'm just happy with my RCS, which are doing really well in my water. You should keep us posted on how your shrimp are doing, sounds like a fun project![]()
