axolotl vs ampullaria
I recently acquired 4 axolotls. Ranging from 1 1/2" to 2 1/2". I also raise apple snails. Apple snails have an operculum or door to their shell that they retract inside when they pull in their foot. The operculum is made of the same material as the shell and therfore hard with sharp edges.
After settling the axolotls into their tank with a few apple snails, I left them alone for about 30 minutes, and when I returned, the largest axolotl (also my only leucistic) had its head inside one of the snails. This particular snail was around 3" in diameter. What probably happened was that when the axolotl investigated, the snail tried to close up into its shell.
xenopus (o Hymenochirus, non ho capito che specie è

) vs cozza
when i was about 15, i had a freshwater mussel with a couple of african dwarf frogs. one day, i found the frogs toes clamped in the mussel. it took 20 minutes of trying to pry the mussel open with a credit card and a butterknife before we got the frog out. they both survived, but i wouldnt keep mussels or clams with anything else after that.
io per sicurezza avevo solo le planorbarius con i tritoni, dato che sono senza opercolo
