Some members have had success keeping apple snails with bettas/fighters, but I did not. I kept my VT Charlie with an apple snail for a short time, until I realized that he had bitten Poppet's antenna off. Poppet NEVER came out of his shell I moved Charlie into temporary housing and Poppet came right out and has been on the go ever since. I think it all comes down to the temperament of the betta in question. I have a feeling my boy Luck, who is in a community tank with guppies, wouldn't have a problem with snails, but Charlie was a total bully.
hmmm....
well so far diablo's killed 2 neons and a shrimp
...
so i named him appropriately
i have a back up tank, if worst comes to worst...
question,
what snails are quicker than a betta (to retreat into their shells)
or are they pretty much the same...?
I also have apple snails and they got harassed frequently from the beginning.
Now they just snail along 'blind' (in their shells) and only truly come out during the night.
I have a 60 litre tank though, so it's peaceful.. most of the time.
