CalmedByFish Posted July 23, 2021 Share Posted July 23, 2021 (edited) I'm getting my first-ever shrimp this weekend! 🙂 They're juvenile neocaridina. I'll be dividing them into 2 tanks, in case 1 tank has a problem I can't detect. I've got all my ducks in a row, with 1 exception. I don't understand how concerned I should be about GH. Currently, 1 tank has GH 13, and the other is GH 19. Good? Bad? Why? Edited July 23, 2021 by CalmedByFish Link to comment Share on other sites More sharing options...
Guppysnail Posted July 23, 2021 Share Posted July 23, 2021 They are surprisingly forgiving. 1 Link to comment Share on other sites More sharing options...
CT_ Posted July 23, 2021 Share Posted July 23, 2021 I know of one online retailer that publishes their parameters and they keep/breed them in up to 15gh. I suspect you're fine. The internet says lower than that is optimal but I suspect, as with most fish too, that stable is all you need.  Why? No idea. I know at really low gh (like 0 or 1) there's issues with a lot of fish because they need some amount of Mg and Ca for their cells to work right.  shrimp also need calcium for their exoskeleton. they can get that from food though if they're getting food with calcium. (my theory is that fish poop from baby brine shrimp is a great source for shrimp) Link to comment Share on other sites More sharing options...
Guppysnail Posted July 23, 2021 Share Posted July 23, 2021 As long as they have some calcium and some magnesium they adjust. The key is what they ere raised in. The transition is the hardest. I ordered from a reputable breeder but on the other coast and they fell apart in my hard water local bred preformed like champs in the same tank. I don’t know all the scientific stuff just what I have observed in my own tanks. Link to comment Share on other sites More sharing options...

CalmedByFish Posted July 23, 2021 Author Share Posted July 23, 2021 This is really helpful. Thank you! I brought the 19 down to 15, so now the tanks are GH 13 and 15. I also asked the current owner what GH these ones are used to, to make sure I don't need to adjust further.  @CT_, if you happen to be referring to the guy I'll just call Rob, I actually emailed them once about a personal matter I thought we might connect on. SUCH sweet people! Link to comment Share on other sites More sharing options...
