Just curious. Obviously I know they had to be introduced to the tank SOMEHOW right?
The tank is 13.5 evo. First wet Beginning of January as a coral and invert only tank
Started with Carib sea life rock, Carib sea live sand and a couple small pieces of live rock from my DT and various bottled bacteria.
January 10th added Mexican turbos, nassarius, and blue hermits
January 26th. I fragged a couple pieces of GSP and glued them to some frag plugs that were both in my DT
Literally nothing else has gone in this tank. I use separate equipment for each tank for maintenance so not to accidentally cross contaminate during the quarantine process.
So riddle me this batman,

Where in the word did these come from? Is it possible that they came from the piece of LIve rock from DT when I set up, or one of the DT frag plugs and just took this long to populate and show numbers? I don't seem to have the problem in my DT but maybe that is because it has fish?
Or if they came in on snail shell in early January, again wouldn't I have seen them before now?
I just moved over quarantined snails from this tank to my DT right before I posted this. So is it safe to assume that if they weren't in my DT, they are likely in my DT now?
I have so many questions HAHAHA
