barbs will screw with the snail.....catfish and plecos are not reccomended because they are also bottom feeders like the apple snail, but i suppose if you have a large enough tank you should be alright. also the pleco eats algae( so does the snail ) so only house the snail and pleco if you intend to add some algae wafers
Hmm thanks, I just wondered if they would be aggressive I have a 35gal tank so It'd be ok if I got more although I'm not planning on doing so. ?And btw, i have 2 snails and I feed them lettuce however they are still great vs. algae.
