curiosity about invertebret reproduction

[rcg49]

If I get multiple hermit crabs, procelain crabs, cleaner shrimp, etc will they reproduce in my tank?

No they will not, they may lay eggs but you would never know & they would never survive. Some snails, however can & will reproduce in your tank.

I have seen baby hermits in my tank in ridiculously tiny snail shells, but don't see any juveniles. Small inverts are just on everyone's menu.

I had a couple Scutus scutus limpet snails hitchhike in on a 6lb liverock that have been multiplying steadily at first at about 1 new snail per week and now...I don't know but I see lots of babies now! I have never seen these offered for sale anywhere but they are sure neat critters. They are film algae grazers and completely harmless (that I've seen). Another good snail that reproduces readily in the tank are Stomatellas. :wavehand: Here are my limpet snails.
