Ramshorns & MTS are suffering but Shrimp & Daphnia are ok???

The tank is a

- 10gal heavily planted w/ val, dwarf sag, & giant duckweed
- agaronite substrate
- Stocked with least killi's, MTS, ramshorns, cherry shrimp, & some daphnia surviving in the substrate
- I used to dose PPS Pro daily but have backed off since this issue
- I typically do a 50% water change and trim monthly with hard water from my well.

Everything in this tank has been healthy for over a year since setup but over the last month the MTS have nearly died out and the ramshorns numbers are dropping. The MTS I do find alive are always held up in their shells. Shrimp and fish are acting normal.

I'm looking at test kits but don't even know what to look for that would cause this. This particular MTS colony is important to me and I want to save it. Thanks in advance.

what are you feeding the snails and shrimp? maybe there's not enough to feed the snails and the population is maxing out

if you're not seeing an impact on the shrimp then I wouldn't bee too worried.

Atm the tank gets .2-tsp of hatched baby brine in the morning, .1-tsp of northfin fry food in the evening, and about once a week or so I'll drop in some northfin kelp pellets. I'm don't think is a lack of food issue, when I feed the ramshorns don't come running they stay held up in their shells. Most recent photo attached.

I've had similar experiences and have found that feeding them (ramshorns, in my case), once a week is fine, with a calcium-rich food helps maintain and grow the population. There may not be enough periphyton, excess food, detritus, etc. for them. The problem becomes trying to prevent the fish from eating the food. So, what I do is to use a snail trap, which is nothing more than a feeder, of this type: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1. For food, I use this: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1, but any similar food that is high in calcium would work. Some people use blanched vegetables such as spinach, but I've found these to make a mess and are hard to control.

If it is not a food issue, is your pH above about 6.5? I've noticed that my ramshorns shells will deteriorate somewhere below that point. Has anything been introduced that contains a surge in copper (water pipes or medicine)?
