I'm having a huge amount of trouble keeping snails and after searching and searching this and other forums, I'm still really stumped as to what's going wrong!
I've tried multiple nerite snails (one by one) and now also an apple snail, and even though they're lively in the bag coming home, once they go into my tank, they struggle and die almost immediately, only moving a very short distance from where they're dropped in, if at all, with long periods of just sitting, before they die within a day or two. The snails were acclimated by floating for an hour to equalize temperature and having the water in their bag nearly drained and replaced by small amounts of tank water (maybe 20%) every 10 mins for that acclimation hour. This last time I tried the snails, I was worried that past ones hadn't been able to find enough food, so I bought algae wafers and literally placed the snails face down on
the wafers when they first went into the tank so that they could get food even if they weren't yet comfortable exploring, but the pattern repeated unchanged. When I first set the tank up, some small "pest" snails hitchhiked in on a plant and did amazingly well (laying eggs and multiplying like crazy for 1-2 months until they died off, presumably from eating all the algae). It was after this, when the algae started to come back, that I tried purchasing snails and have had such poor luck. The plants and fish (one betta) in the tank are doing just fine. The betta was interested in the snails, but I didn't specifically see him attacking them or harassing them too much (and could a betta even harm a grape-sized nerite or apple snail?)
Tank details are as follows:
Set up approx. 4 months ago
Dirted and planted (Miracle Gro Organic Potting Mix topped with gravel but have had the same issues with another tank with Fluval Stratum + gravel cap)
Seachem Prime and Flourish Comprehensive, sometimes Flourish Potassium as needed for hygro polysperma (all state on package that they're invert safe)
Lighting: 18" 6500K LED fixture, 850 lm and 70 PAR @ 12 in
- 10 hour photo period w/ 2 hour break in the middle
Ludwigia repens, hygro polysperma, hygro difformis, bacopa caroliniana, Helanthium tenellum
One betta fish
Test Results (kit expires 04/2023, so should be valid):
Any idea what could be happening? At this point, I don't feel comfortable buying another snail, as their untimely demises seem quite clearly linked to my tank, but I have relatively high lighting and will need algae control again soon, so I'm at a loss.
Any feedback is immensely appreciated - thanks in advance and for reading!
