Please share the tank parameters for...
Do you know/ can you check the pH?
/ Total Dissolved Solids ?
(calcium / alkalinity) / GH
Mine seem to languish in most of the tanks until a pwc
and then they are zipping around. Which in my case makes me think they prefer the higher pH. (maybe) Less TDS
over all? Not sure about that part.
is always low in the tap water nearly 0.
numbers are low 25-33 from tap.
Which means I usually need to put in some minerals - magnesium and calcium to buffer the tank water so the pH doesn't go low - below 6 pH. Okay for some fish too low for some of the others I have.
Anyway, see if you can check the numbers and let's see what your water says. If you can, check the tap water and separately the tank water and see if there are any differences.
You can use the test stick strips for the KH
if you have them. Or the lfs
often will test the water for free, just make sure to write down the readings.
My Nerites may starve, as it seems I can only keep one tough one alive, sometimes (I guess if it IS a tough one). Low pH long term is their enemy in my tanks. Multiples don't work very long in my tanks!
