you could transport them with a permit in the 2000’s now USDA-APHIS inspects for them. I have seen them on eBay and on Aquabid. On eBay most descriptions say you are responsible for the laws in your area. You can almost guarantee they don’t have a permit. In my state they are totally illegal and are supposed to eradicated I found. I just want you guys to be careful. Like I said I had them and enjoyed them when they didn’t destroy my planted tanks(2) I thought in 2019 there was a new law but I don’t follow that closely. 

Learn something new everyday, thanks for the source!

Always wondered why I never found them. Per reading more articles it seems that these guys are omnivores and will polish off everything from plants (including duckweed), soft inverts (so molted snails are going to become dinner) and eggs. These guys seem to be more suited for displays or temporary cleanup crews that get migrated tank to tank knowing what damage they could inflict to everything in the tank.

I keep them to maintain the cycle in my Qt.  They are exceptional at that!  And, they are impressive and very nice looking critters!  I think in low density they are fine as @laritheloud has noted, but I agree, they do not come without risk.

Moral of the story: Keep only one, like I do. 😅 He's super cool, but I have seen him slurp small bladder snails out of their shells and gobble them down. My blue dream shrimps are fine, though, and breeding prolifically!

EDIT TO ADD: I actually bought mine at my local fish store, so I assume they were legal.

Will do. I do ensure he gets fed with Repashy or invert pellets daily and he chows them fully down. The guy has an appetite for sure.

My concern is if I go away on a business trip or vacation... How will they fair with limited regular meals and how will the shrimp mates be seen in terms of tank mate vs dinner.

After a bit more than a month, @Tihshho I can conclusively say they will eat crypts when they are at density.  I think I have to pull them soon.  Interesting experiment though.  Glad I did it.

Thanks for the info. This is definitely something that isn't discussed much about this species. Only the agricultural documents discus flora damage, I had not read any plant damage/destruction experiences by any hobbyists.

So, my CRS bucket is now wildly full of baby snails.  These things can produce!  It's making me think I need puffers...  But that's a story for another thread.

What I wanted to report on was how they have impacted the water in the bucket.  I normally do a 20% daily water change on them because there are about 300+ snails in there, growing fast.  But, I was out of town for 5 days recently,.  Curious, I dipped a strip in to see what the water was at, mostly interested in the nitrates.  And they were high for any of my tanks at about 20ppm.  But what really caught my eye was the weird colors on the other reading on the strip. 

My well water runs at about 8.2pH, a GH of about 300, and a KH of about 180.  Well, in the snail bucket after 5 days the pH was <6.5, the GH was down to about 120, and the KH was zero!  I've never seen numbers like this with my water before! 

So, I think what has happened is there are enough snails in the bucket that to build their shells, they pulled the Ca out of the water, reducing the GH, eliminating the KH, and plunging the pH.  Who knew snails could do that?!  And this is despite the fact I have a huge limestone "ReefSaver" rock in there with them! 

So maybe I can have discus if I just have enough CRS to lower the hardness and pH.  🤪
