I really love snails and want to breed mysteries but am a little tight on space (10 gallon tight.) How would I even go about the breeding process and how many babies would I possibly get?
Mystery snails are different from most snails since they are not hermaphroditic (meaning made of both genders and reproducing asexually), reproduction in mystery snails requires at least 1 male and 1 female in order for there to be babies. The male has a penile tube much like its breathing siphon tube used solely for reproduction (obviously). When Mr. Snail and Ms. Snail pair up, Mr. Snail inserts the tube under the shell of Ms. Snail and enters her body. Its common to see the female carrying the male around. If you can stay up, eggs are generally laid in the night and out of water.
If you get a pair, you will get lots - a clutch can have over 200 eggs although not all will hatch.
I have a black one now in a 10 gallon with a dwarf frog and male betta... Would if be okay to get a few more snails and see if they lay eggs in the tank?
If you get "a few more snails", you could wind up with pairs that will lay eggs. You just have to have a plan for the babies, as your 10 gallon will not be big enough. I have 3 clutches right now that will hatch in 2-3 weeks and already setting up a large separate tank for them. Good luck in your venture! Mystery Snails are so fascinating!
