Rabbit snails are so fun! I have a few in a 16 gallon long with neocaridina shrimp and celestial pearl danios. I haven't had any issues with that combo and regularly find baby rabbit snails.
I also have bladder and ramshorn snails in the tank and I have found that, when they get to abundant, they can outcompeted the rabbit snails (especially the babies). I regularly remove some of the bladder and ramshorn snails to stop that from happening. I feed them green beans regularly and different wafers/shrimp pellets. They don't seem very picky. Have fun with them!
