NO

I'll try my best, but I'm not an expert :) *Sorry for the late reply, I didn't get a comment notification*
A possible explanation for the "out of nowhere" infestation would be that the pet store had snail eggs in their water.
Possible solutions: Avoid overfeeding your fish. Carefully control their portions or feed them a little less than normal. It won't kill them, don't worry. Make sure to check your filter/filter material for eggs (if you have one). You don't want to miss any. Normally, I wouldn't recommend doing a 100% water change, because fish are forced to acclimate quickly to bacteria-free water (they rely on some types of beneficial bacteria). However, this is a more extreme case, so I think you should go ahead. Remove everything you have in the tank (decorations/filter/water) and scrape off all visible snails. Scrub your aquarium, decor, and filter thoroughly with WATER ONLY, soap residue can harm your fish. Dry it, then refill and restock. Hope this helps, good luck! :)

R.I.P. little betta :( My friend has always kept hermit crabs as well! She's very fond of them <3

You better not be talking about MY fish, or we're gonna have a problem buddy...

You heard me. You know the juice that comes out from wringing your bones? Tastes like apple juice :) y u m

Oh! That's a good point, but it doesn't really apply to that child (situation reasons). I'll take note for future stories though :)

Yeah, sure

I always forget to mention that double letters ARE allowed. Thanks for reminding me :)

Oh! I thought you had seen a mantis shrimp on an oatmeal box or something.

The what?

I'm convinced that @nelson has hacked at least 3 accounts

I thought that said gentle frog robot and I was thinking about how cute and terrifying that would be.

Mantis shrimp (technically not a fish, but that goes with the theme of my last request post)
