Back from the dead!

Hmmm...The eggs that I obtained which failed to hatch turned palest pink to white.

Thanks; I doubt it's the same thing as you're mentioning as it seems to happen within 24 hours and may even be immdiate, but the eggs at the very top of the clutches in my tank turn white- I'd assumed these were either drying out or infertile. The eggs are laid JUST above the water line- the area where they've been laid stays quite humid, although less humid than other tanks where there are closer-fitting condensation trays (due to the fitting of the external filter there are some gaps above the water line in this tank).
 
I have noticed that my snails often lay a couple dud clutches initially before producing a fertile one. Also, at least with bridgesii clutches, the fertile clutches get a quite "moldy" appearance a day or two before hatching. You cannot so much see the baby snails as there is a discoloration of the eggs and the sac in between gets much whiter. I remember reading over at applesnail of many people having a difficult time getting their cana clutches to hatch. It may be worth it, if you want to hatch them, to do a hatchery technicque in order to provide consistent temp and humidity. Good luck, and please post pics as cana's are not as commonly kept here in the states. I would love to see your snails.
 
Hi Jinx- to me they don't look much different to the other species of apples, but I'm not an invert expert! I don't have any recent pics but this is them a couple of months ago- they've grown a bit since then, but not massively, and are also in a different tank now...

Apologies for dirty tank glass!
 
Those are definitely canas, and lovely ones at that! Nice job, they look very healthy.

Cana eggs seem to take a little longer to hatch than brig eggs, but they don't seem to need as much care as brig clutches. I didnt' have any problems with any of mine. Before trying to swirl out the babies, wait until you see the clutch starting to hatch. If about a quarter of the clutch has already hatched naturally, then it's time to help the rest out.

It could be a dud clutch. My cana eggs retain their bright pink/orange color right up until they start hatching. They don't turn that whitish color that brig clutches do. Every snail is different, but that seems to be normal.

Don't worry though, once they start laying there's no stopping them.

Thanks for the info- I'll try leaving the remaining 3 clutches a bit longer before interfering!
 
Well after messing up spawn one, most of clutch two must have been viable as they hatched today. I really thought the clutch had fungused, but picking it up the remains were almost like polystyrene. They've laid again so I've still got three clutches.

I'm hoping the tank's not too tall for the babies- it's an 18" tall tank, probably with 14" depth of water- is this OK or do I need to move them?
 
Thanks Jinxzy :)
