I've been cultivating blue mystery snails (also known as apple snail or Pomacea Bridgesii) in a tank for feeding purposes and I've had a population explosion!!!!
Right now I have way more snails than my puffer fish could ever eat. The eggs just hatched a few weeks ago and I don't want to flush the little guys.
Their parents are purely blue colored (no ugly green/brown color on the body or shell) and are really cool looking. They have tiny magenta spots on their midnight blue bodies and antenna and pale blue shells (just like the picture below). I've put some of my bigger snails in my regular tank for cleaning purposes and I've since developed an affinity for them. They climb up to the top of the tank and surf down to the bottom using their foot as a parachute. This color has gotten really popular lately for aquarists, when I first started breeding this type of snail the blue color was rare and now it's semi-common (still nowhere near as common was golden mystery snails). However the kind sold in major chain stores tend to be mixed color and you can never be sure how yours will grow up to look. My snails are parasite free, since I feed them to my fish I have to keep them very healthy.
I've been using them for fish food so I don't blame anyone for wanting to start a feeder tank of their own. Clown loaches love them, so do puffers, leporinus and blue loaches. these are really easy animals to care for once they get to be about three months old. They generally live 6-10 months in aquariums, but I have had most of mine live up to two years. They will be marble sized when they are ready to re-home but they will grow to be a little bigger than golf ball sized.
If you would like to get one as a pet or to start a feeder tank I can advise you on proper feeding, water temp, etc. FYI, these are very hardy freshwater snails. The only things I have seen that will harm them are copper based aquarium medication and overly saline (salty) aquarium water. They can only stand about 1 - 3% salt solution in their tanks.
I would like a re-homing fee of $1.50 for a single snail or $5.00 for 5 snails. These guys sell for around $3 - $6 each at local fish stores, so I'm not gouging anyone. This is to re-coup some of the expense of feeding/housing them until they are of an adoptable age (When there are this many they eat a lot!).
They wont be ready to re-home until December 1st. I'm hoping to have homes for all of them by Christmas. Since I have so many I have had to buy a separate tank and I need the space in my living room for my Christmas tree.
