Absolutely. I'm researching how to keep the PH low enough to keep them happy rn. Even a buffering substrate + salty bee alone doesn't cut it, since they need a 5.5-6.7. I would need a lot of driftwood, very little plants (maybe just a tiny amount of floaters - salvina, not the dreaded duckweed), and a constant supply of botanicals for all of the tannins. Now I understand why all of the rare pinto breeders have such sparse tanks. I always wondered why they have so very little plants.
I'm wondering if the PH regulators would help.. though I'm sure it would somehow kill super sensitive caridina. I know a lot of people experience losses even with the right parameters, and spending $500 at a time on shrimp just to have them die under the perfect conditions isn't a deal breaker for me. I went through much of the same keeping finches.
I had very rare color variations and I was always pretty much trying to keep them alive. Spending $1k at a time on breeding stock is a must. At one point I had a whole finch room with racks of cages, and larger aviaries in my living room. The only reason I stopped is when my brother died and everything kind of took a back seat to my grief. I prefer the challenge and keeping/breeding rare color variations is worth it. That's the best way imho to elevate any breeding hobby.
With Flip Aquatics, they have a 30 day holding period for their imported + rare caridina variations. That is huge since imported shrimp tend to die for no reason (or many reasons) during that time frame according to everything I've read/watched. That's a giant leg up. There is also a breeder I just found nearby - The Grove Aquatics - with the rarer variations. If they can provide the same 30 day buffer or if they have tank bred then I'm in business with 2 different lines to start with.
