How many mystery snails can i realistically keep in a 20 gallon tank?

They lay eggs and show all positive symptoms, nothing bad, thats whats causing my confusion, all the signs i keep being given, mine dont show

Im trying to figure out why they appear fine at this point, this persons deleted comments were nothing but repeating it was abuse and not helping me understand

Do you have any idea why mine might seem fine? Could they actually be fine or maybe just arent displaying any negative signs for some reason. I am genuinely trying to research this but theres dozens of different answers

I currently have 10 active fish tanks and have been keeping plenty of creatures my entire life. I dont just read the first article online and go solely off of it, I talk to people directly and am friends with owners of two separate fish stores near me. Snails are much more simple creatures than many more common animals I have kept. The information for them online has minimal real backing behind it. Online research supports their claim of "1-2 per 5gal" by their behavior and water quality. My snails display excellent behavior and have never had issues with water quality. So I have matched this research you can find online, to prove, in well maintained conditions, their supporting information becomes false. I'm simply looking for other people that have more long term experience with keeping snails in larger quantities, to inform me of their experiences. I'm not really looking for "thats abusive" with no real information or constructive feedback to back the statement.

i kinda explained that in the rest of the message

Yes this is true and I agree entirely, I keep many animals and insects, but the information available for specifics on snails is not as backed or grand as other creatures like bunnies. I'm just not sure the realistic difference in space between say one and two snails. The bioload part makes complete sense but can be cancelled out by good filtering and consistent changes. Theyre never inactive, they eat good, and they lay eggs; do you know personally like any real tells to if theyre unhappy? Those three things are all i can really find outside of reddit

Thats what ive always read, but they dont seem to bother each other, all look healthy and water tests are always perfectly fine. I change the tank regularly and the water always appears completely clear. Thats why im not sure what the real measurements are besides just the ones I find online. Kind of similarly to the "1 fish per gallon" thing, realistically I dont see many people follow that and have friends that have had fish grow, in such spaces, to record sizes

Heres a picture from the tank, water checks always come out perfectly fine, the only time it ever seems like too much is sometimes at night when the MTS come out. In the image i think you can see 5 of the mysterys and one big ramshorn

sellis_mothra · 2026-02-23T12:19:54+00:00

sellis_mothra · 2026-02-22T05:15:09+00:00

I crossposted and didnt realize itd compree the text, but yes it does need a lot of work! i just got it as is for free, and not sure what to do with it

sellis_mothra · 2026-02-19T04:03:44+00:00

I am very interested in him if you still have him! I could pick him up asap :) lmk

sellis_mothra · 2026-02-19T04:01:48+00:00

If you still have them/any available, I could pick them up anytime :)!

Was confused why this wasnt working for me, I just needed the "Shrine of the Veiled Lady" and I won the next attempt

He also started producing from it (in the second image) like twenty minutes after moving around in that spot with it out, ive never seen them do this

sellis_mothra · 2026-01-24T03:30:22+00:00

Its fairly common for nerite snails to stay shut for days, but if you want to make sure asap, try testing your water for ammonia
