Hello everyone!

First of all, let me introduce myself! I'm Felipe Aoki and I'm from Brazil.

I have these amazing little guys in all of my tanks. Thet help A LOT when it comes to controlling algae. A little one layed it's eggs on the front glass, so I could take some very nice pictures! :D here they go:

The happy couple breeding (note the little tube they use to exchange sperm):

Right after the ritual, the tube is even more visible:

The eggs right after the laying:

After 24hs, the little white dots have taken some shape, but not much:

After 48hs, the little snails can be very clearly seen inside the eggs. Note the little eyes and shells:

After 72hs, the hatching. I's amazing to watch, because with help of a 20x magnification, I could see the huge struggle they have to go through to hatch the eggs. So little, so strong :bounce:

Hope you guys enjoy it!

Bye!! :wave:
